New York City says it's speeding up a plan to equip all its police officers and detectives on patrol with body cameras.

More than 20,000 cameras will be in use in the 34,000 member department by the end of this year.  The mayor of New York says the policing tool that records officers' actions will build trust with communities.

The Police commissioner says his department is moving forward faster after getting positive feedback from commands already using about 2,500 body cameras.  Here's more from WILX-TV 10.
