molson - If a police officer uses his or her weapon to kill a person, there should be an outside, independent investigation. That doesn't happen for the most part (
which is described in this great piece on Politico). Life is sacred. When you take someone's life you better have a damn good reason.
And with respect to the taser - my second most pressing question, albeit far behind why the kid needed to be shot 6 times. It mystifies me why it wasn't used. What about that situation required lethal force?
