My 18yr old has a lock on his door for when he goes out. He is an adult and has the right to privacy. He has a lot of expensive computer equipment so it's as much for burglar prevention. I really don't think this is that unusual, especially in cities with high crime rates.
It's absolutely disgusting what the policeman said to her, I really feel if this was a white, pretty, blonde 19yr old the response would have been very different. Honestly are London police trying to pee off the pubic on purpose??! MOO
