I watched the video and didn't see the actual shooting. However, unless the therapist did something radically different than what he was doing in the clip I saw, I would agree that the cop messed up big time.
Since the guy was only wounded, I wonder why they aren't showing the actual shooting... or did I miss it?
Oh, it gets worse. According to the police, the officer may have been aiming at the autistic man.
