Putting cameras on the police is a great idea, specially for the cops that are rightfully doing their job. Without that video the cop could have made up any story about that shooting, even if there was an eye witness. That video looks like the cop did throw something down by the body, probably was the taser that he had earlier used. Shooting a guy in the back while fleeing is just wrong. I wonder if shooting someone in the back while fleeing is justified if the guy had just killed someone or had wounded the officer.
