Glad he's OK. He sure was lucky surviving three shots at point blank...
Shooting back at the car as it drove away was a mistake, but it perfectly highlights how so many cops too often get crap for doing what anybody else in the same situation would have done. As police officers they are expected to display exemplary behaviour under all circumstances, they cannot afford to act as "anybody else" would have, the public and the law demand they be better, above the rest, but they're still people. They get annoyed, run out of patience, get scared or all pumped up on adrenaline and do things maybe they wouldn't have done in a more peaceful state of mind.
Glad he didn't hit any innocents, but with the adrenaline, shock and pain, most of his shots probably went several feet over trafic anyway
