Might make a good alibi, though, for someone thinking ahead. All you need is a reliable accomplice who can take your smartphone for a very traceable outing, complete with FB comments, while you head in the other direction to commit whatever mayhem you had in mind.

Or just duct tape it to your neighbors car and retrieve it later. That way you don't have to worry about an accomplice spilling the beans.

No no no... duct tape leaves a residue... maybe hide it on top of an EXIT sign in a darkened movie theatre for an afternoon matinee? (Make sure you do actually see the movie first, so you can describe it convincingly.)
