New York City started trying police body cameras years ago, but it hasn't had a formal agreement to roll them out across the entire force. It's not for lack of trying, though -- the city and the officers' union have been locked in contract negotiations for ages. An agreement is finally in place, however. As part of a new contract, the NYPD will equip every officer with a body camera by the end of 2019. When there are over 34,000 officers patrolling the streets, this could easily be one of the most ambitious body camera projects to date.
