Never mind that it's a side door.
Never mind that you can't tell if a door is locked unless you try it.
Never mind that anyone trying to open a stranger's door probably doesn't have a whole lot of nice things in mind.
Leave your door unlocked and get assaulted and raped, at least according to one big-mouthed member of the RCMP.
Here's my letter to the editor, feel free to write your own:
I'm sure anyone with criminal intent is very comforted to know that Cpl. Buxley will excuse rape & assault on the basis of an unlocked door which isn't visible from the street. How nice for the bad guys.
I'm so ticked I can't see straight right now.
