I’ve seen the video and stepped through it frame by frame numerous times. It was about three seconds.
How was the man an immediate threat with his back turned to him. Also, the taser was on the ground when he was running. So I’m not sure where you’re getting your info.
No there are three video cameras. And in court they are longer. What you saw was edited for the news. As each cop arrives there is another camera. The first cop who pulls over the guy has a camera in his car. The second cop has a camera and records the shooting. He is black. A third cop records the first cop throwing down the gun. All the cameras are running for a while. Plus the second cop, a large black guy, sees the first cop throw down the gun and asks him to pick it up again.
You have several views, you have several witnesses who are cops. This is open and shut.
