Lots of people are suggesting that buglers exit through a window. Assuming that the windows aren't safety glass and the thieves don't take there sweet time to avoid nicking themselves, allowing the police to get there, then that method might wind up having the thief leave behind DNA instead of picking it up, which doesn't really help him avoid being arrested. The biggest problem would be that thieves generally wear mask anyways so if they ditch their cloths then there won't be anything to track them by, but by the same logic, it'd be hard to track them if they ditch there cloths anyways. At least now if they arrest the guy in short order or he doesn't ditch all his cloths then they can catch him red handed.
