Lots of dumb advice in this thread. Engaging in a physical confrontation that could have been avoided is always dumb. The guy might have a weapon, he might be cracked out and not feel fear or pain. He might come back later armed. He might come back later after seeing your fancy gun and steal all your fancy guns for some easy cash. You might lose. You also might pummel him like a true Billy Badass and then he lawyers up and cleans you out. You KO him with one swing like John Wayne but he dies, now you're going to prison. Even confronting him in a threatening way is a big risk because you don't know what he's capable of. Just stupid.

Best outcome is that he voluntarily leaves, after being convinced he wants to by the police or someone besides you. Next best outcome is that someone else makes him leave, like law enforcement.

The only reason I am doing this guy harm is if he's in my house and I have no other choice. Even then, do you know the size of the checks you're going to be writing to lawyers to try to stay out of jail? And the further stacks when his family lawyers up to try to piggybank you?

The worst thing that could happen is that he does you harm, the second worst thing that could happen would be if you did some to him.
