On a different note, we had this problem at home with the next door neighbors (my parents own their house but the one next to ours is privatly rented)
When they were playing really loud music at 3am my dad phone the police and the guy came banging on our door at home (I was about 8 or 9) punches were thrown and the guy stood on my dads foot and ran off, my dad still has problems as the guy broke his foot.
moral of this. If your going to open the door to someone hostile always wear shoes.....I have my rigger boots next to the door with steel toe caps

that for now.
