(1) From subsections (c)(3), (c)(4), and (d) to the extent that access to records in this system of records may impede or interfere with law enforcement efforts, result in the disclosure of information that would constitute an unwarranted invasion of the personal privacy of collateral record subjects or other third parties, and/or jeopardize the health and/or safety of third parties.

(2) From subsection (e)(1) to the extent that it is necessary to retain all information in order not to impede, compromise, or interfere with law enforcement efforts, e.g., where the significance of the information may not be readily determined and/or where such information may provide leads or assistance to Federal and other law enforcement agencies in discharging their law enforcement responsibilities.

(3) From subsection (e)(2) because, in some instances, the application of this provision would present a serious impediment to law enforcement since it may be necessary to obtain and verify information from a variety to sources other than the record subject to ensure safekeeping, security, and effective law enforcement. For example, it maybe necessary that medical and psychiatric personnel provide information regarding the subject's behavior, physical. health, or mental stability, etc. to ensure proper care while in custody, or it may be necessary to obtain information from a case agent or the court to ensure proper disposition of the subject individual.

(4) From subsection (e)(3) because the requirement that agencies inform each individual whom it asks to supply information of such information as is required by subsection (e)(3) may, in some cases, impede the information gathering process or otherwise interfere with or compromise law enforcement efforts, e.g., the subject may deliberately withhold information, or give erroneous information.

(5) From subsection (4)(G) and(H) because the application of these provisions would present a serious impediment to law enforcement efforts.

(6) From subsection (e)(5) because in the collection of information for 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 and the accuracy of such information can only be determined in a court of law. The restrictions imposed by subsection (e)(5) would restrict the ability to collect information for law enforcement purposes, may prevent the eventual development of the necessary criminal intelligence, or otherwise impede law enforcement or delay trained law enforcement personnel from timely exercising their judgment in managing the arrestee.

(7) From subsection (e)(8) to the extent that such notice may impede, interfere with, or otherwise compromise law enforcement and security efforts.

(8) From subsection 5 U.S.C. 552a(f) to the extent that compliance with the requirement for procedures providing individual access to records, compliance could impede, compromise, or interfere with law enforcement efforts.

(9) From subsection (g) to the extent that this system is exempt from the access and amendment provisions of subsection (d).
