(1) From subsection (c)(3) because this subsection is inapplicable to the extent that an exemption is being claimed for subsection (d).

(2) From subsection (c)(4) because this subsection is inapplicable to the extent that an exemption is being claimed for subsection (d).

(3) From subsection (d) because access to the records contained in this system may interfere with or impede an ongoing investigation as it may be related to allegations against an agent or witness who is currently being investigated. Further, other records that are derivative of the subject's employing agency files may be accessed through the employing agency's files.

(4) From subsection (e)(1) because it may not be possible to determine in advance if potential impeachment records collected and maintained in order to sufficiently meet the Department's Giglio requirements and obligations are all relevant and necessary. In order to ensure that the Department's prosecutors and investigative agencies receive sufficient information to meet their obligations under Giglio, it is appropriate to maintain potential impeachment information in accordance with Department policy as such records could later be relevant and necessary in a different case in which the same witness or affiant subsequently testifies.

(5) From subsection (e)(2) because collecting information directly from the subject individual could serve notice that the individual is the subject of investigation and because of the nature of the records in this system, which are used to impeach or demonstrate bias of a witness, requires that the information be collected from others.

(6) From subsection (e)(3) because federal law enforcement officers receive notice from their supervisors and prosecuting attorneys that impeachment information may be used at trial. Law enforcement officers are also given notice by the Giglio decision itself.

(7) From subsections (e)(4)(G), (H), and (I) because this system of records is exempt from the access and amendment provisions of subsection (d).

(8) From subsection (e)(5) because it may not be possible to determine in advance if all potential impeachment records collected and maintained in order to sufficiently meet the Department's Giglio requirements and obligations are all accurate, relevant, timely, and complete at the time of collection. Although the Department has policies in place to verify the records, the records may be originated from another agency, third party, or open source media and it may be impossible to ensure the accuracy, relevance, timeliness, and completeness of potential impeachment information maintained prior to and during the process of being verified.

(9) From subsection (e)(8) because the nature of the Giglio discovery process renders notice of compliance with the compulsory discovery process impractical.

(10) From subsections (f) and (g) because these subsections are inapplicable to the extent that the system is exempt from other specific subsections of the Privacy Act.
