(1) Central Criminal Division, Index File and Associated Records System of Records (JUSTICE/CRM-001) - Limited Access. This system of records and associated exemptions is adopted by and applies with equal force and effect to the National Security Division, until modified, superseded, or revoked in accordance with law.

(2) General Crimes Section, Criminal Division, Central Index File and Associated Records System of Records (JUSTICE/CRM-004) - Limited Access.

These exemptions apply to the extent that information in those systems are subject to exemption pursuant to 5 U.S.C. 552a (j)(2), (k)(1) and (k)(2).

(1) . (c)(3). The release of the disclosure accounting for disclosures made pursuant to subsection (b) of the Act, including those permitted under the routine uses published for these systems of records, would permit the subject of an investigation of an actual or potential criminal, civil, or regulatory violation to determine whether he is the subject of investigation, or to obtain valuable information concerning the nature of that investigation, and the information obtained, or the identity of witnesses and informants and would therefore present a serious impediment to law enforcement. In addition, disclosure of the accounting would amount to notice to the individual of the existence of a record; such notice requirement under subsection (f)(1) is specifically exempted for these systems of records.

(2) . (c)(4). Since an exemption is being claimed for subsection (d) of the Act (Access to Records) this subsection is inapplicable to the extent that these systems of records are exempted from subsection (d).

(3) . (d). Access to the records contained in these systems would inform the subject of an investigation of an actual or potential criminal, civil, or regulatory violation of the existence of that investigation, or the nature and scope of the information and evidence obtained as to his activities, of the identity of witnesses and informants, or would provide information that could enable the subject to avoid detection or apprehension. These factors would present a serious impediment to effective law enforcement because they could prevent the successful completion of the investigation, endanger the physical safety of witnesses or informants, and lead to the improper influencing of witnesses, the destruction of evidence, or the fabrication of testimony.

(4) . (e)(1). The notices of these systems of records published in the Federal Register set forth the basic statutory or related authority for maintenance of this system. However, in the course of criminal or other law enforcement investigations, cases, and matters, the Criminal Division or its components will occasionally obtain information concerning actual or potential violations of law that are not strictly within its statutory or other authority or may compile information in the course of an investigation which may not be relevant to a specific prosecution. In the interests of effective law enforcement, it is necessary to retain such information in these systems of records since it can aid in establishing patterns of criminal activity and can provide valuable leads for federal and other law enforcement agencies.

(5) . (e)(2). In a criminal investigation or prosecution, the requirement that information be collected to the greatest extent practicable from the subject individual would present a serious impediment to law enforcement because the subject of the investigation or prosecution would be placed on notice as to the existence of the investigation and would therefore be able to avoid detection or apprehension, to influence witnesses improperly, to destroy evidence, or to fabricate testimony.

(6) . (e)(3). The requirement that individuals supplying information be provided with a form stating the requirements of subsection (e)(3) would constitute a serious impediment to law enforcement in that it could compromise the existence of a confidential investigation or reveal the identity of witnesses or confidential informants.

(7) . (e)(4) (G) and (H). Since an exemption is being claimed for subsections (f) (Agency Rules) and (d) (Access to Records) of the Act these subsections are inapplicable to the extent that these systems of records are exempted from subsections (f) and (d).

(8) . (e)(4)(I). The categories of sources of the records in these systems have been published in the Federal Register in broad generic terms in the belief that this is all that subsection (e)(4)(I) of the Act requires. In the event, however, that this subsection should be interpreted to require more detail as to the identity of sources of the records in these systems, exemption from this provision is necessary in order to protect the confidentiality of the sources of criminal and other law enforcement information. Such exemption is further necessary to protect the privacy and physical safety of witnesses and informants.

(9) . (e)(5). In the collection of information for criminal law enforcement purposes it is impossible to determine in advance what information is accurate, relevant, timely, and complete. With the passage of time, seemingly irrelevant or untimely information may acquire new significance as further investigation brings new details to light and the accuracy of such information can often only be determined in a court of law. The restrictions of subsection (e)(5) would restrict the ability of trained investigators, intelligence analysts, and government attorneys in exercising their judgment in reporting on information and investigations and impede the development of criminal or other intelligence necessary for effective law enforcement.

(10) . (e)(8). The individual notice requirements of subsection (e)(8) could present a serious impediment to law enforcement as this could interfere with the ability to issue warrants or subpoenas and could reveal investigative techniques, procedures, or evidence.

(11) . (f). Procedures for notice to an individual pursuant to subsection (f)(1) as to the existence of records pertaining to him dealing with an actual or potential criminal, civil, or regulatory investigation or prosecution must be exempted because such notice to an individual would be detrimental to the successful conduct and/or completion of an investigation or prosecution pending or future. In addition, mere notice of the fact of an investigation could inform the subject or others that their activities are under or may become the subject of an investigation and could enable the subjects to avoid detection or apprehension, to influence witnesses improperly, to destroy evidence, or to fabricate testimony.

Since an exemption is being claimed for subsection (d) of the Act (Access to Records) the rules require pursuant to subsection (f) (2) through (5) are inapplicable to these systems of records to the extent that these systems of records are exempted from subsection (d).

(12) . (g). Since an exemption is being claimed for subsections (d) (Access to Records) and (f) (Agency Rules) this section is inapplicable, and is exempted for the reasons set forth for those subsections, to the extent that these systems of records are exempted from subsections (d) and (f).

(13) . In addition, exemption is claimed for these systems of records from compliance with the following provisions of the Privacy Act of 1974 (5 U.S.C. 552a) pursuant to the provisions of 5 U.S.C. 552a(k)(1): Subsections (c)(3), (d), (e)(1), (e)(4) (G), (H) and (I) and (f) to the extent that the records contained in these systems are specifically authorized to be kept secret in the interests of national defense and foreign policy.

(1) . (c)(3) The release of the disclosure accounting for disclosures made pursuant to subsection (b) of the Act, including those permitted under the routine uses published for these systems of records, would permit the subject of an investigation of an actual or potential criminal violation, which may include those protected under the Witness Security Program, to determine whether he is the subject of a criminal investigation, to obtain valuable information concerning the nature of that investigation and the information obtained, or the identity of witnesses and informants and the nature of their reports, and would therefore present a serious impediment to law enforcement. In addition, disclosure of the accounting would amount to notice to the individual of the existence of a record; such notice requirement under subsection (f)(1) is specifically exempted for these systems of records. Moreover, disclosure of the disclosure accounting to an individual protected under the Witness Security Program could jeopardize the effectiveness and security of the Program by revealing the methods and techniques utilized in relocating witnesses and could therefore jeopardize the ability to obtain, and to protect the confidentiality of, information compiled for purposes of a criminal investigation.

(2) . (c)(4) Since an exemption is being claimed for subsection (d) of the Act (Access to Records) this section is inapplicable.

(3) . (d) Access to the records contained in these systems would inform the subject of an investigation of an actual or potential criminal violation, which may include those protected under the Witness Security Program, of the existence of that investigation, of the nature and scope of the information and evidence obtained as to his activities, of the identity of witnesses and informants, or would provide information that could enable the subject to avoid detection or apprehension. These factors would present a serious impediment to effective law enforcement because they could prevent the successful completion of the investigation, endanger the physical safety of witnesses or informants, and lead to the improper influencing of witnesses, the destruction of evidence, or the fabrication of testimony. In addition, access to the records in these systems to an individual protected under the Witness Security Program could jeopardize the effectiveness and security of the Program by revealing the methods and techniques utilized in relocating witnesses and could therefore jeopardize the ability to obtain, and to protect the confidentiality of, information compiled for purposes of a criminal investigation.

(4) . Exemption is claimed from subsection (e)(1) for the reasons stated in subsection (b)(4) of this section.

(5) . (e)(2) In the course of preparing a Witness Security Program for an individual, much of the information is collected from the subject. However, the requirement that the information be collected to the greatest extent practicable from the subject individual would present a serious impediment to criminal law enforcement because the individual himself may be the subject of a criminal investigation or have been a participant in, or observer of, criminal activity. As a result, it is necessary to seek information from other sources. In addition, the failure to verify the information provided from the individual when necessary and to seek other information could jeopardize the confidentiality of the Witness Security Program and lead to the obtaining and maintenance of incorrect and uninvestigated information on criminal matters.

(6) . (e)(3) The requirement that individuals supplying information be provided with a form stating the requirements of subsection (e)(3) would constitute a serious impediment to law enforcement in that it could compromise or reveal the identity of witnesses and informants protected under the Witness Security Program.

(7) . (e)(4) (G) and (H). Since an exemption is being claimed for subsections (f) (Agency Rules) and (d) (Access to Records) of the Act these subsections are inapplicable.

(8) . (e)(4)(I). The categories of sources of the records in these systems have been published in the Federal Register in broad generic terms in the belief that this is all that subsection (e)(4)(I) of the Act requires. In the event, however, that this subsection should be interpreted to require more detail as to the identity of sources of the records in the system, exemption from this provision is necessary in order to protect the confidentiality of the sources of criminal law, enforcement information and of witnesses and informants protected under the Witness Security Program.

(9) . Exemption is claimed from subsections (e)(5) and (e)(8) for the reasons stated in subsection (b)(9) and (b)(10) of this section.

(10) . Procedures for notice to an individual pursuant to subsection (f)(1) as to the existence of records contained in these systems pertaining to him would inform the subject of an investigation of an actual or potential criminal violation, which may include those protected under the Witness Security Program, of the existence of that investigation, of the nature and scope of the information and evidence obtained as to his activities, of the identity of witnesses and informants, or would provide information that could enable the subject to avoid detection or apprehension. These factors would present a serious impediment to effective law enforcement because they could prevent the successful conduct and/or completion of an investigation pending or future, endanger the physical safety of witnesses or informants, and lead to the improper influencing of witnesses, the destruction of evidence, or the fabrication of testimony. In addition, notices as to the existence of records contained in these systems to an individual protected under the Witness Security Program could jeopardize the effectiveness and security of the Program by revealing the methods and techniques utilized in relocating witnesses and could therefore jeopardize the ability to obtain, and to protect the confidentiality of, information compiled for purposes of a criminal investigation.

Since an exemption is being claimed for subsection (d) of the Act (Access to Records) the rules required pursuant to subsection (f) (2) through (5) are inapplicable.

(11) . (g) Since an exemption is being claimed for subsections (d) (Access to Records) and (f) (Agency Rules) this section is inapplicable and is exempted for the reasons set forth for those subsections.

(1) . (c)(3). The release of the disclosure accounting for disclosures made pursuant to subsection (b) of the Act, including those permitted under the routine uses published for these systems of records, would permit the subject of an investigation of an actual or potential criminal violation to determine whether he is the subject of a criminal investigation and would therefore present a serious impediment to law enforcement. The records in these systems contain the names of the subjects of the files in question and the system is accessible by name of the person checking out the file and by name of the subject of the file. In addition, disclosure of the accounting would amount to notice to the individual of the existence of a record; such notice requirement under subsection (f)(1) is specifically exempted for these systems of records.

(2) . (c)(4). Since an exemption is being claimed for subsection (d) of the Act (Access to Records) this section is inapplicable.

(3) . (d). Access to the records contained in these systems would inform the subject of an investigation of an actual or potential criminal violation of the existence of that investigation. This would present a serious impediment to effective law enforcement because it could prevent the successful completion of the investigation, endanger the physical safety of witnesses or informants, and lead to the improper influencing of witnesses, the destruction of evidence, or the fabrication of testimony.

(4) . Exemption is claimed from subsections (e)(4) (G), (H) and (I) for the reasons stated in subsections (b)(7) and (b)(8) of this section.

(5) . (f). These systems may be accessed by the name of the person who is the subject of the file and who may also be the subject of a criminal investigation. Procedures for notice to an individual pursuant to subsection (f)(1) as to the existence of records pertaining to him, which may deal with an actual or potential criminal investigation or prosecution, must be exempted because such notice to an individual would be detrimental to the successful conduct and/or completion of the investigation or prosecution pending or future. In addition mere notice of the fact of an investigation could inform the subject or others that their activities are under or may become the subject of an investigation and could enable the subjects to avoid detection or apprehension, to influence witnesses improperly, to destroy evidence, or to fabricate testimony.

Since an exemption is being claimed for subsection (d) of the Act (Access to Records) the rules required pursuant to subsection (f) (2) through (5) are inapplicable.

(6) . (g). Since an exemption is being claimed for subsections (d) (Access to Records) and (f) (Agency Rules) of the Act this section is inapplicable and is exempted for the reasons set forth for those subsections.

(1) . (c)(4). Since an exemption is being claimed for subsection (d) of the Act (Access to Records) this section is inapplicable to the extent that this system of records is exempted from subsection (d).

(2) . (d). The records contained in this system of records generally consist of information filed with the court in response to the request and made available to the requestor. To the extent that these records have been so filed, no exemption is sought from the provisions of this subsection. Occasionally, the records contain pertinent logs of intercepted communications and other investigative reports not filed with the court. These records must be exempted because access to such records could inform the subject of an investigation of an actual or potential criminal violation of the existence of that investigation and of the nature of the information and evidence obtained by the government. This would present a serious impediment to effective law enforcement because it could prevent the successful completion of the investigation, endanger the physical safety of witnesses or informants, and lead to the improper influencing of witnesses, the destruction of evidence, or the fabrication of testimony.

(3) . Exemption is claimed from subsections (e)(4) (G), (H) and (I) for the reasons stated in subsections (b)(7) and (b)(8) of this section.

(4) . (f). The records contained in this system of records generally consist of information filed with the court and made available to the requestor. To the extent that these records have been so filed, no exemption is sought from the provisions of this subsection. Occasionally, the records contain pertinent logs of intercepted communications and other investigative reports not filed with the court. These records must be exempted from a requirement of notification as to their existence because such notice to an individual would be detrimental to the successful conduct and/or completion of a criminal investigation or prosecution pending or future. In addition, mere notice of the existence of such logs or investigative reports could inform the subject or others that their activities are under or may become the subject of an investigation and could enable the subjects to avoid detection or apprehension, to influence witnesses improperly, to destroy evidence, or to fabricate testimony.

Since an exemption is being claimed for subsection (d) of the Act (Access to Records) the rules required pursuant to subsection (f) (2) through (5) are inapplicable to the extent that this system of records is exempted for subsection (d).

(6) . (g). Since an exemption is being claimed for subsections (d) (Access to Records) and (f) (Agency Rules) this section is inapplicable, and is exempted for the reasons set forth for those subsections, to the extent that this system of records is exempted from subsections (d) and (f).

(1) Information File on Individuals and Commercial Entities Known or Suspected of Being Involved in Fraudulent Activities System of Records (JUSTICE/CRM-006).

(2) The Stocks and Bonds Intelligence Control Card File System of Records (JUSTICE/CRM-021).

(3) Tax Disclosure Index File and Associated Records (JUSTICE/CRM-025).

These exemptions apply only to the extent that information in these systems is subject to exemption pursuant to 5 U.S.C. 552a(j)(2).

(1) (c)(3) The release of the disclosure accounting for disclosures made pursuant to subsection (b) of the act, including those permitted under the routine uses published for these systems of records, would permit the subject of an investigation of an actual or potential criminal violation to determine whether he is the subject of a criminal investigation, to obtain valuable information concerning the nature of that investigation, and the information obtained, or the identity of witnesses and informants, and would therefore present a serious impediment to law enforcement. In addition, disclosure of the accounting would amount to notice to the individual of the existence of a record; such notice requirement under subsection (f)(1) is specifically exempted for this system of records.

(2) (c)(4) Since an exemption is being claimed for subsection (d) of the act (access to records), this section is inapplicable to the extent that these systems of records are exempted from subsection (d).

(3) (d) Access to the records contained in these systems would inform the subject of an investigation of an actual or potential criminal violation of the existence of that investigation, of the nature and scope of the information and evidence obtained as to his activities, of the identity of witnesses and informants, or would provide information that could enable the subject to avoid detection or apprehension. These factors would present a serious impediment to effective law enforcement because they could prevent the successful completion of the investigation, endanger the physical safety of witnesses or informants, and lead to the improper influencing of witnesses, the destruction of evidence, or the fabrication of testimony.

(4) Exemption is claimed from subsections (e) (1), (2), and (3), (e)(4) (G), (H), and (I), (e)(5) and (e)(8) for the reasons stated in subsections (b)(4), (b)(5), (b)(6), (b)(7), (b)(8), (b)(9), and (b)(10) of this section.

(5) (f) Procedures for notice to an individual pursuant to subsection (f)(1) as to the existence of records pertaining to him dealing with an actual or potential criminal investigation or prosecution must be exempted because such notice to an individual would be detrimental to the successful conduct and/or completion of an investigation or prosecution pending or future. In addition, mere notice of the fact of an investigation could inform the subject or others that their activities are under or may become the subject of an investigation and could enable the subjects to avoid detection or apprehension, to influence witnesses improperly, to destroy evidence, or to fabricate testimony. Since an exemption is being claimed for subsection (d) of the act (access to records), the rules required pursuant to subsection (f) (2) through (5) are inapplicable to these systems of records.

(6) (g) Since an exemption is being claimed for subsections (d) (access to records) and (f) (Agency rules), this section is inapplicable and is exempted for the reasons set forth for those subsections.

(1) . Exemption is claimed from subsections (c) (3) and (4) and (d) for the reasons stated in subsections (j)(1), (j)(2) and (j)(3) of this section.

(2) . (e)(1). The notice for this system of records published in the Federal Register sets forth the basic statutory or related authority for maintenance of this system. However, in the course of criminal investigations, cases, and matters, the Organized Crime and Racketeering Section will occasionally obtain information concerning actual or potential violations of law that are not strictly within its statutory or other authority, or may compile information in the course of an investigation which may not be relevant to a specific prosecution. In the interests of effective law enforcement, it is necessary to retain such information in this system of records since it can aid in establishing patterns of criminal activity and can provide valuable leads for federal and other law enforcement agencies.

(3) . Exemption is claimed from subsections (e) (2) and (3), (e)(4) (G), (H) and (I), (e) (5) and (8), (f) and (g) for the reasons stated in subsections (b)(5), (b)(6), (b)(7), (b)(8), (b)(9), (b)(10), (b)(11) and (b)(12) of this section.

(4) . In addition, exemption is claimed for this system of records from compliance with the following provisions of the Privacy Act of 1974 (5 U.S.C. 552a) pursuant to the provisions of 5 U.S.C. 552a(k)(1): Subsections (c)(3), (d), (e)(1), (e)(4) (G), (H) and (I) and (f) to the extent that the records contained in this system are specifically authorized to be kept secret in the interests of national defense and foreign policy.

(1) . (c)(3). The release of the disclosure accounting for disclosures made pursuant to subsection (b) of the Act, including those permitted under the routine uses published for these systems of records, would permit the subject of an electronic interception to obtain valuable information concerning the interception, including information as to whether he is the subject of a criminal investigation, by means other than those provided for by statute. Such information could interfere with the successful conduct and/or completion of a criminal investigation, and would therefore present a serious impediment to law enforcement. In addition, disclosure of the accounting would amount to notice to the individual of the existence of a record; such notice requirement under subsection (f)(1) is specifically exempted for these systems of records.

(2) . (c)(4). Since an exemption is being claimed for subsection (d) of the Act (Access to Records) this section is inapplicable.

(3) . (d). Access to the records contained in these systems would inform the subject of an electronic interception of the existence of such surveillance including information as to whether he is the subject of a criminal investigation by means other than those provided for by statute. This could interfere with the successful conduct and/or completion of a criminal investigation and therefore present a serious impediment to law enforcement.

(4) . (e)(2). In the context of an electronic interception, the requirement that information be collected to the greatest extent practicable from the subject individual would present a serious impediment to law enforcement because the subject of the investigation or prosecution would be placed on notice as to the existence of the investigation and this would therefore destroy the efficacy of the interception.

(5) . (e)(3). The requirement that individuals supplying information be provided with a form stating the requirements of subsection (e)(3) would constitute a serious impediment to law enforcement in that it could compromise the existence of a confidential electronic interception or reveal the identity of witnesses or confidential informants.

(6) . (e)(4) (G) and (H). Since an exemption is being claimed for subsections (f) (Agency Rules) and (d) (Access to Records) of the Act these subsections are inapplicable.

(7) . Exemption is claimed from subsections (e)(4)(I) and (e)(8) for the reasons stated in subsections (b)(8) and (b)(10) of this section.

(8) . (f). Procedures for notice to an individual pursuant to subsection (f)(1) as to the existence of records pertaining to him dealing with an electronic interception other than pursuant to statute must be exempted because such notice to an individual would be detrimental to the successful conduct and/or completion of an investigation pending or future. In addition, mere notice of the fact of an electronic interception could inform the subject or others that their activities are under or may become the subject of an investigation and could enable the subjects to avoid detection or apprehension, to influence witnesses improperly, to destroy evidence, or to fabricate testimony.

Since an exemption is being claimed for subsection (d) of the Act (Access to Records) the rules required pursuant to subsection (f)(2) through (5) are inapplicable to these systems of records to the extent that these systems of records are exempted from subsection (d).

(9) . (g). Since an exemption is being claimed for subsection (d) (Access to Records) and (f) (Agency Rules) this section is inapplicable, and is exempted for the reasons set forth for those subsections, to the extent that these systems of records are exempted from subsection (d) and (f).

(1) . (c)(3). Release of the accounting of disclosures made pursuant to subsection (b) of the Act, including those permitted under the routine uses published for this system of records, (a) as to a witness for whom immunity has been proposed, would inform the individual of the existence of the proposed immunity prematurely, thus creating a serious impediment to effective law enforcement in that the witness could flee, destroy evidence, or fabricate testimony; and (b) as to a witness to whom immunity has been granted, or for whom it has been denied, would reveal the nature and scope of the activities, if any, of the witness known to the government, which would also create a serious impediment to effective law enforcement.

(2) . (c)(4). Since an exemption is being claimed for subsection (d) of the Act (Access to Records) this section is inapplicable to the extent that this system of records is exempted from subsection (d).

(3) . (d). Access to the records contained in this system (a) as to a witness for whom immunity has been proposed, would inform the individual of the existence of the proposed immunity prematurely, thus presenting a serious impediment to effective law enforcement in that the witness could flee, destroy evidence, or fabricate testimony; and (b) as to a witness to whom immunity has been granted, or for whom it has been denied, would reveal the nature and scope of the activities, if any, of the witness known to the government, which would also create a serious impediment to effective law enforcement.

(4) . (e)(2). In a witness immunity request matter, the requirement that information be collected to the greatest extent practicable from the subject individual would present a serious impediment to law enforcement because the subject of the immunity request and often the subject of the underlying investigation or prosecution would be placed on notice as to the existence of the investigation and would therefore be able to avoid detection or apprehension, to influence witnesses improperly, to destroy evidence, or to fabricate testimony.

(5) . Exemption is claimed from subsections (e)(3), (e)(4)(G), (H) and (I), and (e)(8) for the reasons stated in subsections (b)(6), (b)(7), (b)(8) and (b)(10) of this section.

(6) . (f). Procedures for notice to an individual pursuant to subsection (f)(1) as to the existence of records pertaining to him (a) as to a witness for whom immunity has been proposed, would inform the individual of the existence of the proposed immunity prematurely, thus presenting a serious impediment to effective law enforcement in that the witness could flee, destroy evidence, or fabricate testimony; and (b) as to a witness to whom immunity has been granted, or for whom it has been denied, would reveal the nature and scope of the activity, if any, of the witness known to the government, which would also create a serious impediment to effective law enforcement.

Since an exemption is being claimed for subsection (d) of the Act (Access to Records) the rules required pursuant to subsection (f)(2) through (5) are inapplicable to this system of records to the extent that this system of records is exempted from subsection (d).

(7) . (g). Since an exemption is being claimed for subsections (d) (Access to Records) and (f) (Agency Rules) this section is inapplicable, and is exempted for the reasons set forth for those subsections, to the extent that this system of records is exempted for subsections (d) and (f).

(8) . In addition, exemption is claimed for this system of records from compliance with the following provisions of the Privacy Act of 1974 (5 U.S.C. 552a) pursuant to the provisions of 5 U.S.C. 552a(k)(1): subsections (c)(3), (d), (e)(1), (e)(4) (G), (H) and (I) and (f) to the extent that the records contained in this system are specifically authorized to be kept secret in the interests of national defense and foreign policy.

(1) Freedom of Information/Privacy Act Records (JUSTICE/CRM-024)

These exemptions apply to the extent that information in this system is subject to exemption pursuant to 5 U.S.C. 552a(j)(2), (k)(1) and (k)(2).

(1) (c)(3). The release of the disclosure accounting would present a serious impediment to law enforcement by permitting the subject of an investigation of an actual or potential criminal, civil, or regulatory violation to determine whether he is the subject of investigation, or to obtain valuable information concerning the nature of that investigation and the information obtained, or to identify witnesses and informants.

(2) (c)(4). Since an exemption is being claimed for subsection (d) of the Act (Access to Records), this subsection is inapplicable to the extent that this system of records is exempted from subsection (d).

(3) (d). Access to records contained in this system would enable the subject of an investigation of an actual or potential criminal or civil case or regulatory violation to determine whether he or she is the subject of investigation, to obtain valuable information concerning the nature and scope of the investigation, and information or evidence obtained as to his/her activities, to identify witnesses and informants, or to avoid detection or apprehension. Such results could prevent the successful completion of the investigation, endanger the physical safety of witnesses or informants, lead to the improper influencing of witnesses, the destruction of evidence, or the fabrication of testimony, and thereby present a serious impediment to effective law enforcement. Amendment of the records would interfere with ongoing criminal law enforcement proceedings and impose an impossible administrative burden by requiring criminal investigations to be continuously reinvestigated.

(4) (e)(1). In the course of criminal or other law enforcement investigations, cases, and matters, the Criminal Division will occasionally obtain information concerning actual or potential violations of law that are not strictly within its statutory or other authority, or it may compile information in the course of an investigation which may not be relevant to a specific prosecution. In the interests of effective law enforcement, it is necessary to retain such information since it can aid in establishing patterns of criminal activity and can provide valuable leads for Federal and other law enforcement agencies.

(5) (e)(2). To collect information to the greatest extent practicable from the subject individual of a criminal investigation or prosecution would present a serious impediment to law enforcement. The nature of criminal and other investigative activities is such that vital information about an individual can only be obtained from other persons who are familiar with such individual and his/her activities. In such investigations it is not feasible to rely upon information furnished by the individual concerning his own activities.

(6) (e)(3). To provide individuals supplying information with a form stating the requirements of subsection (e)(3) would constitute a serious impediment to law enforcement in that it could compromise the existence of a confidential investigation or reveal the identity of witnesses or confidential informants.

(7) (e)(4) (G) and (H). These subsections are inapplicable to the extent that this system is exempt from the access provisions of subsection (d) and the rules provisions of subsection (f).

(8) (e)(4)(I). The categories of sources of the records in this system have been published in the Federal Register in broad generic terms in the belief that this is all that subsection (e)(4)(I) of the Act requires. In the event, however, that this subsection should be interpreted to require more detail as to the identity of sources of the records in this system, exemption from this provision is necessary to protect the confidentiality of the sources of criminal and other law enforcement information. Such exemption is further necessary to protect the privacy and physical safety of witnesses and informants.

(9) (e)(5). In the collection of information for criminal law enforcement purposes it is impossible to determine in advance what information is accurate, relevant, timely, and complete. With the passage of time, seemingly irrelevant or untimely information may acquire new significance as further investigation brings new details to light and the accuracy of such information can often only be determined in a court of law. The restrictions of subsection (e)(5) would inhibit the ability of trained investigators, intelligence analysts, and government attorneys in exercising their judgment in reporting on information and investigations and impede the development of criminal or other intelligence necessary for effective law enforcement.

(10) (e)(8). The individual notice requirements of subsection (e)(8) could present a serious impediment to law enforcement as this could interfere with the ability to issue warrants or subpoenas and could reveal investigative techniques, procedures, or evidence.

(11) (f). This subsection is inapplicable to the extent that this system is exempt from the access provisions of subsection (d).

(12) (g). Because some of the records in this system contain information which was compiled for law enforcement purposes and have been exempted from the access provisions of subsection (d), subsection (g) is inapplicable.

(1) Access to records contained in this system could inform the subject of the identity of witnesses or informants. The release of such information could present a serious impediment to effective law enforcement by endangering the physical safety of witnesses or informants; by leading to the improper influencing of witnesses, the destruction of evidence, or the fabrication of testimony; or by otherwise preventing the successful completion of an investigation.
