Preventing Authoritarian Policing Tactics on America's Streets Act This bill imposes limitations on federal law enforcement officers and members of the Armed Forces (or the National Guard) engaging in law enforcement activities related to crowd control. When engaged in certain law enforcement activities related to crowd control, such an officer or member (1) shall clearly display certain identifying information, such as the individual's last name or unique identifier; and (2) shall not use an unmarked vehicle to apprehend or arrest civilians. Such an officer or member may only engage in certain law enforcement activities, such as crowd or riot control and arrest of individuals engaged in civil disobedience, on or in the immediate vicinity of federal property, unless (1) a state or local government has requested federal support, or (2) the President has invoked certain authorities to suppress insurrection. If such an officer or member is conducting a law enforcement function in violation of the limitations in this bill, the officer or member may not arrest an individual in the United States. If such an officer or member is deployed to respond to any riot, public disturbance, or crowd control incident, the responsible federal agency or branch of the Armed Forces shall, within 24 hours of the deployment, notify the public and provide certain information on its website.
