The guy sounds like the kind of guy who shouldn’t own a gun, now someone is dead because of him.
The claim is that he went down there waving his gun around, shot into the air, and shot into the ground, and then admits shooting a guy who wasn’t threatening him.
Besides, legalities aside, if you end up killing someone while yelling at rafters who stop on your river bank, then you are not exactly a picture of a rational man.
As I read it, he yelled at them to get off his property, and instead of doing so the husband grabbed the homeowner’s arm, so the homeowner shot him.
I would try to make a case saying he was shot in self defense.
Did you not read the part where the vistim grabbed the shooter's arm or the part where some of the party approached the guy with the gun with rocks in their hands?
