JM 8-3.170
Frequently, conduct which deprives persons of federally protected rights in violation of federal law also violates state law. In such cases, where state and local authorities undertake prosecution in state courts, it is Department of Justice policy to cooperate with the local prosecutor unless there is a good faith basis that is supported by the law, the facts, or other established Department of Justice Policy, to disagree with the state’s decision to prosecute or with its conduct of a prosecution.
Any release of reports of investigative materials should be undertaken in accordance with 28 C.F.R. Part 16 and §§ 1-6.000 et seq. of the JM.
