Best question yet.
Sounds to me that the child had a lot more judgment than the dead dad.
I think you are right. I’ve been thinking about this sad scenario. Anything Weaver had to discuss with the shooter could have waited...except one thing. If Weaver wanted to confront the shooter *while* he was drinking, that could not have waited. If, for example, Weaver had gone the next day, the shooter [sorry; I don’t know his name off hand] could have said, ‘I only had a couple of beers.’ Weaver could not have proved otherwise.
So the one matter so urgent that the dead father just couldn’t let it ride would have been the drinking itself. For whatever reason, Weaver wanted to crash the party and be obnoxious about the fact that alcohol was being consumed. [This is pure conjecture, but it fits what facts we have.] For this he should not have been shot, but again, we don’t know where that “confrontation” went from there. Just a shame it couldn’t have waited till the next day regardless.
Yes, the son did have more sense. Get away and stay away. If only his Dad had followed suit.
