DENVER (AP) - Some Denver police officers are using body cameras on patrol as part of a study of their effectiveness.
Officers assigned to the downtown area began wearing the cameras in June for the six-month study being conducted by Taser International and the University of Cambridge.
The fatal police shooting of an unarmed black 18-year-old in Ferguson, Missouri, has prompted calls for more officers to wear the cameras, simple, lapel-mounted gadgets that capture video footage of law enforcement's interactions with the public. Proponents say the devices add a new level of accountability to police work.
Denver police chief Robert White plans to talk about the department's use of the cameras at a press conference Wednesday afternoon.
