The buzz around my apartment building has been about mail theft. It seems that a car parked in our narrow, one-car-wide driveway over the weekend and one (at least) mailbox was entered and its mail torn up. The police think they know who's doing it and think these people have a master mailbox key. Now when the mail arrives there's a stampede to get one's mail before someone else does.
You'd think there'd be an app for this. Maybe there is. I'd like to see combination locks, that can be reset, on the mailboxes.
