Its ok saying youll kick the crap out of them but this never really solves the problem.
Happened to me before where the cars where getting done every weekend, and I mean EVERY weekend, but we could never catch them. One night I looked out the window and seen 3 guys coming along the street, I waited to see if they done anything and guess what, they tried to punch in my window.
I ran out of the house, cleared my gate and flew at the guy who done it. KOd and out for the count the guy who done it was obviously taught a lesson, then I realised I was standing in the middle of the street, 2 guys against me and their mate beat 2 a pulp. To my EXTREME luck an off duty police officer walked by as me and the other 2 were in the "ready to go for it" situation. The other prat gradually came round and the three of them done a runner.
Not only was I lucky that the other 2 never had a serious go at me, I worried for ages that they where gonna come back in bigger crowds, with weapons..etc, throw bricks through my parents windows, petrol bomb my car, whatever.
Just no winning
