Title 18 U.S.C. § 1114 extends the protection of 18 U.S.C. § 111 to a diverse collection of Federal government personnel. The primary focus of the Department's enforcement program is on those employees who have law enforcement duties which regularly expose them to the public (e.g., agents of the FBI, DEA, ATF, Secret Service, IRS, Customs, Postal Inspectors, etc.) and on staff members of Federal correctional institutions. Forcible acts against these categories Federal employees should be prosecuted vigorously. By contrast, offenses against other categories of Federal employees should be referred to the local prosecutor unless the offense is particularly aggravated or there are other unusual factors present justifying Federal action.
