What is the specificity of a defendant's request for in-chambers review of officer records?

"This specificity requirement excludes requests for officer information that are irrelevant to the pending charges. [Citation.] And it enables the trial court to identify what types of officer misconduct information, among those requested, will support the defense or defenses proposed to the pending charges. This inquiry establishes the statutorily required materiality prong of the good cause showing that a defendant must make to receive in-chambers review of potentially relevant officer records." (Warrick v. Superior Court, supra, 35 Cal.4th at pp. 1021-1022.)
