London's police department says it will roll out vest-mounted video cameras to some of the capital's 2,300 firearms officers, hoping to help build public confidence in the force by allowing jurors and judges to literally see things from an officer's perspective.

Thursday's announcement came a day after a jury largely vindicated London police over a fatal shooting of a gang member that triggered rioting across England more than two years ago.

Police says armed officers will begin wearing recording devices on April 1. The number of officers set to wear the cameras has yet to be decided.

Police forces across the world have been experimenting with portable cameras as tools for crime-fighting and police accountability.
