Here is a comprehensive compilation of Baton Laws by States on the civilian carry of batons, also called nightsticks or billy clubs, in each state of the US. The baton is a roughly cylindrical club weapon used predominately by law enforcement, corrections, and security personnel as a less-than-lethal measure. The possession and use of any other device capable of firing/launching a projectile (e.g., paintball guns, water balloon and potato launchers, cannons, catapults and slingshots) is prohibited.
