6. The officer could have shot him in the leg(s) prior to head but obviously wanted to kill Michael Brown.
If 5 is true, 6 shouldn't have happened because unless he was armed the officer was not (in my mind) justified in using deadly force. The officer could have just as easily grabbed his pepper spray or taser if he thought this unarmed person 150ft away from him was a threat. If you or I were in the position the police officer was in, even without us being armed with "less lethal" weapons, we'd be facing a murder charge if we opened fire on him and would rightly be convicted and serve life in prison, if not the death penalty.
