Oh well, okay, some houses have those locks. Others still have latches on the outside as well as inside, which is ridiculous in my opinion because if you forget to lock the door at night then anyone can just walk in and rob/kill/rape you! My country seems to be rather confused when it comes to domestic security. :S
And apparently I'M confused about domestic security as well. When I say we don't lock our doors from inside, I mean we actually have locks AS WELL as a keyhole. I don't see much point in that extra keyhole though since most houses here in England have Yale locks for the resident to get in if they have a key, which isn't required if they want to get out. Needing a key to leave your house is just plain daft.
We have locks like Danish ones in the U.S. too. I don't think there's any door in this country that locks from the inside. The locks you're used to are called security bolts in the U.S., though, because we actually have two separate locks on our front doors: one on the doorknob, which keeps the doorknob from being turned, and the security bolt, which is in case you forget to lock the doorknob. Bad neighborhoods will sometimes have small chains that go across the door and hook into a fixture on the wall. That way, if you leave the first two unlocked for some stupid reason, it makes it harder for criminals to get in. Bad neighborhoods also have a metal mesh door on the outside of the normal door with the same two-lock system. We're really paranoid in American ghettos. It is perfectly normal for a house in a downtown urban area to have a minimum of five locks on two separate doors.
You have raised an excellent point. e_e
