Title 18 › PART I — CRIMES › CHAPTER 44 — FIREARMS › § 930
You cannot knowingly bring or try to bring a gun or any other dangerous weapon into most federal buildings. If you do, you can be fined or jailed for up to 1 year. If you bring a weapon into a federal building intending to use it to commit a crime, the penalty can be a fine or up to 5 years in prison. Bringing a weapon into a federal court building is also illegal and can bring a fine or up to 2 years in jail, unless one of the listed exceptions applies. If someone kills another person while doing these acts or while attacking a federal facility with a weapon, they will be punished under the federal murder and manslaughter laws. Authorized law officers, federal officials or military members acting under law, and people carrying weapons for lawful activities like hunting are allowed in many cases. Federal courts can set their own weapon rules and punishments for people in court buildings. Definitions: Federal facility — a building owned or leased by the U.S. where federal employees work regularly. Dangerous weapon — anything that can cause death or serious harm (except a pocketknife blade under 2½ inches). Federal court facility — courtrooms and related rooms and corridors. Notice about the rules must be posted at public entrances; if it is not posted you cannot be convicted unless you actually knew the rule.
