No Respect Anymore!!!!

Okay.... Believe we officially have the neighbor from hell!!! We moved into our home in 2007 and it was bearable. I mean they were loud, but we managed. If it wasn't their 3 kids screaming and yelling, the husband working on his many vehicles revving up the engines, or his target shooting. Okay.... in come 2k10 they finally move, Must Say this was the Most Peaceful Time of our Whole time here!!!!! Then I guess someone started using the house for band practice (very loud again), then they went away. Peace at last, or soooooo I thought. Now someone has moved in and I think the dude is Really Insane!!! He plays music at weird times of the night. I'm talking like 9pm and later. It was sooooo loud one nite I actually called the police, but then I thought he had finally stopped so I called and cancelled the call. Then it's the target shooting. My baby was sitting at the table a couple of weeks ago doing her homework and she was scared!!! As I'm writing this right now his music is still going!!! I mean he's really getting on my nerves. I don't want to get the police involved because I don't know him or if he's rational at all, (don't think he is by his total disprespect for his neighbors) but I Do Know that Something has to Give!!!! I've prayed that he would just go away!!! I think I might send him a nice letter asking him to just keep his noise down and be more respectful of his neighbors!! I mean we purchased our home and should have every right to enjoy every inch of it in Peace!!! Maybe if I pray hard enough things will get better?!!!
