No, I think it's a great idea. If that whole Minority Report thing happens, you'll have an extra identity.
Blackburn, people will steal anything that isn't bolted down. I can't remember which major city it was, but some town had their sanitation workers go on strike for a long time. Supposedly, you could wrap your garbage up like a Christmas present, leave it in the car with the windows rolled down, and somebody would steal it. I've never had anything big stolen from me (car, TV, guns, etc.), but I still want five minutes alone with the thieves who stole a couple of little things. I believe that our criminal justice system is still the best, but I think we stopped taking thievery seriously when we stopped cutting off thieves' hands.
