As of August 2018, at least 16 states had passed use-of-force laws, according to the nonpartisan National Conference of State Legislatures.
Other laws created task forces to set new standards, boosted training or improved tracking of officers' use of guns and deadly force.
Police unions have often resisted attempts to restrict officers' use of deadly force and are politically potent in most states.
In 2015, the board adopted statewide standards limiting use of deadly force by police officers to defending themselves or others from serious injury or death.
