Never go by yourself to confront. After you confirm, call the cops. There's so many loopholes in the law that can come right around and bite you even though you're the victim.You drive up to the location and you see his house. Then you wait. Confirm by the pictures and confirm target.
You are free to eliminate target. Lol.
No but seriously, confirm it's him and then you go upfront to him. Maybe record the whole session as well?
Then you have enough material to get him in prison in the STATES M.F, maybe I don't know the rules there.
