SACRAMENTO, Calif. (AP) – California lawmakers are working to find common ground between law enforcement groups and reformers intent on adopting first-in-the-nation standards designed to limit fatal shootings by police. A state Senate committee on Tuesday linked a police-backed measure requiring more training with a competing proposal allowing officers to open fire only if they have exhausted non-lethal methods of resolution or de-escalation. It’s a move aimed at forcing negotiations between the sides by combining the most progressive elements of each plan. The combined measure would set a national precedent by creating statewide guidelines on when officers can use deadly force and requiring that every officer be trained in ways to avoid opening fire. The shooting last year of unarmed vandalism suspect Stephon Clark in Sacramento inspired the effort to restrict when police can use their guns in the nation’s most populous state.
