Ah. That's not really physically possible with those we have here - short of wrecking the thing or picking the lock.

I don't see why anyone would though. A bunch of stolen outgoing mail is going to contain nothing but boredom. Certainly nothing you could turn into easy cash.

Though I could picture vandals throwing firecrackers or something into them. In fact I remember something about a PO box burning down being on the local news some time ago. It certainly happens.
