I'm not a police officer; they should be held to a higher standard of discretion since they are permitted a legal monopoly on lethal force in most circumstances.
So police officers should be able to subdue 300 pound men that punch them in the face and break bones while they are charged at them?
I can't imagine how this it is the cops fault, that while injured, he couldn't subdue an angry 300 pound man without use of a gun. Is he supposed to be able to out wrestle him? Does he have to risk his life because the guy isn't armed? If Brown takes the officers guy, how many people would he kill with it?
