Whats the most unsafe/dangerous place youve ever lived in and why? Can you describe what made it dangerous?

I had a lovely house, then a crack head moved in next door. Caught him peeping in my window. Called the cops and he threatened to kill me. Eventually it got so bad I had police protection. One night they were attempting to arrest him (drunk driving) and he tried to kill a police officer. He went to jail for a long time.
