POLICE ENDORSE RECORDING: Wearing A Badge, And A Video Camera.

William A. Farrar, the police chief in Rialto, Calif., has been investigating whether officers’ use of video cameras can bring measurable benefits to relations between the police and civilians. Officers in Rialto, which has a population of about 100,000, already carry Taser weapons equipped with small video cameras that activate when the weapon is armed, and the officers have long worn digital audio recorders.

But when Mr. Farrar told his uniformed patrol officers of his plans to introduce the new, wearable video cameras, “it wasn’t the easiest sell,” he said, especially to some older officers who initially were “questioning why ‘big brother’ should see everything they do.”

He said he reminded them that civilians could use their cellphones to record interactions, “so instead of relying on somebody else’s partial picture of what occurred, why not have your own?” he asked. “In this way, you have the real one.”
