My only auto robbery was when parked near the old Kingdome for a Mariners game. I never lock my doors, the wife always does. I left mine unlocked, as usual, the wife locked hers, as usual. Some dumb ass punched out the lock on her side and stole a few things. Would have been much less expensive if they had just opened my unlocked door.

With these smash and grabs getting more common, maybe leaving the doors unlocked and your valuables in the trunk makes some sense.
