Sure, bull right in, attack the homeowner. Get shot, have a nice day.
On the other hand, call the cops ahead of time, get witnesses, possibly get ex busted for violating court orders - yeah, that works out a lot better, actually.
All I was saying is the fact that the dad was agitated did not make him a “worthless, violent punk”. He wasn’t smart and should have backed off when confronted with a gun, but his anger is understandable if you have ever been in that position.
