Or, this is a middle aged business executive responding to a shotgun pointed at him and emptying the magazine to stop the threat as the SUV rockets away.
Yes, he made a mistake, a big one, in not calling the police to the scene. But, how many people here on FR make stupid comments about shoot, shovel, and shut up? People are not always thinking the clearest after a deadly force encounter.
You assume that he knew that he had hit and killed someone, but there is no reason to believe that he knew that he even hit anyone.
Well we know for a fact that he shot and killed someone, but we don’t know for a fact that a shotgun was pointed at him.
Why play the internet weirdo and start working on a long imaginative narrative about a shooting that you don’t know about yet, but are determined to try and pretend that what little we do know isn’t real, while your narratives are?
So far, the facts are that this guy killed a man, fired shots at a fleeing car, and then got his girlfriend and fled to a motel.
This guy is in some serious trouble.
