Shooting him wasn't the first thing he did. The article states the police officer was kicked and punched in the face multiple times. He didn't shoot him for coming at him with a chair, he was getting a beat down.
Well then I guess the deputy needs to be retrained or find another job. Because if his only viable option during a confrontation is to shoot then the deputy is in the wrong line of work.
I am not picking on the deputy. They showed pictures of the kid on the news last night. My daughter could take him. There is obviously more to the story than what has been released so far but based on the facts released this deputy needs more training in self defense
