I've never been shot at, but I suspect there is probably a very aggressive response that humans have to be shot at. A response serves well in most situations, not so much in this one.
I'd love to see more training for the police officers to help in situations, but I don't see tax payers wanting to pay for it.
My outrage really isn't at the police officers actions, but I understand being outraged about it. My outrage is at the courts. Although I do understand it appears this gentleman may have selected the wrong court.
