When police departments around the country have mandated body cameras, both uses of force by officers and public complaints have often dropped dramatically. Starting Monday, the Los Angeles Police Department will issue 860 body cams — the first of a planned 7000 – to LAPD's Mission Division, which covers Sylmar, Panorama and other parts of the San Fernando Valley. Next up will be the Newton Division in South Los Angeles. But, even though the Police Commission, the police department and the police union agree they're a good idea, many questions remain. When do the cameras have to be turned on…or off? Can cops look at the video before they make official reports? When will the public be able to see the pictures? We hear different views from some of the major players.
