Replying to what would u do ??

so my bro and me get home from work the other day to find his cd s lying on the ground beside his truck, didnt think anything of it just that they dropped out when he was getting out the night before and didnt notice, so later on when he gets in the truck he notices that all his shit had been rummadged threw. so he looked around to see if anything was missing but nothing was, BUT it just happens that the focker that broke into his truck must ve drop his wallet with all his id and all his shit in it on the floor of my bros truck.so we know were this kid lives which is like 2 blocks from our house... so, what would u do ??? go to his house drag him out and kick the shit out of him infront of his family or just not do anything?

i kinda think we should show this guy a lesson
