What you said about the jewelry made me wonder about the electronics. Forgive me if this is a ridiculous question (I'm an Android girl- no Apple experience whatsoever), but do iPad users have to register their devices? I mean if you have an iPad and I decide to steal it, once I do a factory reset, can I use it freely without fear of anyone finding out I have it? Or is there a registration process involving, say, a serial number that would make that risky on my part? If it is impossible to trace the devices back to whoever stole them, you might be on to something. If they can be traced somehow, I'd say the only reason they were stolen was to destroy the devices and delete incriminating data.
