Report: Denver police officers' body cameras didn't record most use-of-force incidents

A report by Denver's independent police monitor says body cameras used by officers in the city's downtown district didn't record most of the use-of-force incidents they should have captured.

The report released Tuesday comes as law enforcement agencies rush to equip officers with cameras after protests over police killings nationwide.

Officers in Denver's downtown district wore the cameras for six months. Mitchell looked at 80 documented force cases in the district during the trial period and found cameras recorded only 21 of them.

Officers said they often weren't able to activate the cameras in the heat of the moment, but Mitchell says they should be turning on the cameras before making contact with citizens.

Experts say the report highlights the cameras' shortcomings and the need for firm policies for their use.
