Police killings of unarmed residents in Missouri, New York and elsewhere have prompted an array of proposed policy changes as legislatures across the nation began their new sessions.
Many of the proposals seek to expand or mandate the use of cameras attached to officers' uniforms. Others would require more training for law officers, tighter limits on when they can use deadly force and the appointment of special prosecutors when police kill people.
In Missouri alone, lawmakers have filed more than 40 measures stemming from the fatal shooting of a black 18-year-old by a white Ferguson policeman. Elsewhere, some lawmakers are looking to bolster protections for police in response to the sometimes violent protests and the shooting of two New York officers after the chokehold death of a black man.
