Although it didn't mention it - the absolute first thing the guy should have done once he heard the gunfire and scream was to report the incident, call 911, even before investigating further.
Look at it from the cop's point of view - they arrive to a scene where they've been told that there was violence and gunfire and there behold is a guy with a shotgun. The cops would be on him in an instant, bagged and tagged and handcuffed the "good deeder" if he was lucky; shot dead in a mistaken identity if he was unlucky. Think again, did he really display good judgement?
Perhaps he should have called 911 first, but I am by no means sure of that. Equally likely: the 911 operator's SOP would be to keep the caller on the phone as long as needed to get all the details needed for response, and at the point where he heard the screams, he did not have those details. IMHO the time involved with the 911 operator would have kept him from going to the victim's aid.
As I read the article, when he saw the victim's injuries, he handed the shotgun to a bystander while he applied a tourniquet. How the bystander handled the gun when police arrived is not clear, but since there is no mention of his arrest, etc., the emergency response personnel apparently did not feel threatened by the situation. The point is, the guy who was fired can hardly be accused of brandishing a weapon, and I don't agree that he used poor judgment under the facts made public so far.
