Two windows were broken in my jeep, along with sugar in the gas tank. I know a person who is friends with the guy who did it, but nobody saw him do it. The cops said there wasnt much they could do if nobody saw them do it. The guy i know was with him, but bailed when he heard that theyre going to mess with my car. What can i do? should i bypass the police and beat his ass? i know where he lives.
