Ant, it really sucks that you had your stuff stolen and I hope that you find who did it and when you do you put a thumpin' on them that they won't soon forget, but this booby trap thing can only end badly for you. Assuming you don't go to jail you can get sued. Having your wages garnered for the rest of your life because of some douchebag as definitely not worth it.
I urge you to rethink this. Hell I'd be willing to come over and help you figure out a way to catch the guy, but I'm afraid if he falls, you are the one that will be sorry.
Seriously, consider the consequences. Adapt and overcome.
