The police officer has given multiple stories and been caught doing it. He shot the guy with no reason to do so. Sounds like murder to me.
Also I would have you know that I'm not an anarchist. I know how important having a well trained, well funded, and well educated police force is to society.
What you should know is that I also have zero tolerance for anyone "accidentally" shooting someone. Guns don't kill people, people kill people, right?
