Title 18 › Part PART I— - CRIMES › Chapter CHAPTER 44— - FIREARMS › § 930
It makes it a crime to knowingly bring or have a gun or other dangerous weapon in a federal building (but not a federal court room). If you do, you can be fined and/or go to jail for up to 1 year. If you have a weapon there because you plan to use it to commit a crime, the penalty can be a fine and/or up to 5 years in jail. Bringing a weapon into a federal court facility can bring a fine and/or up to 2 years in jail. If someone kills another person while doing these acts or while attacking a federal building with a weapon, they are punished under federal homicide laws (sections 1111, 1112, 1113, and 1117). The rule does not apply to officers or employees who are doing official law enforcement work, to federal officials or military members carrying weapons when the law allows it, or to people lawfully carrying weapons for hunting or other legal purposes. Federal courts can also punish contempt or make rules about weapons in their buildings. Signs about the rules must be posted at public entrances, and you cannot be convicted under these rules if no sign is posted unless you actually knew about the rule. Definitions: federal facility (federal-owned or leased workplace), dangerous weapon (anything that can cause death or serious injury, except a pocketknife with a blade under 2½ inches), federal court facility (courtrooms and related rooms).
