JM 9-61.610
United States Attorneys and the Special Agent-In-Charge (SAC) of the local field division of the Federal Bureau of Investigation (FBI) should meet with their State and local counterparts to arrive at a proper allocation of investigative and prosecutive resources for bank robberies being committed in their respective districts. It continues to be Department policy to reduce Federal involvement in the bank robbery area, and make deliberate progress toward maximum feasible deferral of bank robbery matters to those State and local law enforcement agencies which are prepared to handle them. However, no case should be deferred in favor of State/local investigation or prosecution where the state/local law enforcement authorities will not adequately handle it.
