Will police body cameras be replaced by gun-mounted cameras?
A handful of police departments are going beyond body cameras, and testing gun-mounted cameras.
Supporters of the idea say it’s too easy for a body camera’s view to be blocked by an arm or a wall; and sometimes a body camera isn’t even turned on.
Gun-mounted cameras turn on automatically when a gun is drawn from its holster.
But critics say, they don’t record the confrontation that led to the gun being drawn.
