I've only seen the one video so far, but to me it looked like a couple of things happened. The cop seemed to struggle with getting the gun out of the suspects pocket, so it wouldn't appear that was really a threat to the officers, and if you're attempting to arrest the man, why hadn't you turned him onto his stomach? He didn't seem to be resisting too much that they wouldn't have been able to do that. Why did they continue to leave him on his back? Maybe someone in law enforcement could explain that to me. I think there was an issue with the suspect resisting, but from what I saw in my limited viewing and limited knowledge of the situation, the cops handled it excessively.
