What can I do about bad neighbors noise and doing drugs?

I can totally relate to your issues! We have neighbors that are the same only they are a family with a lunatic 24 year old son who has mental problems. He is dangerous and the other day my 18 year old daughter told me she caught hin peeking in the front window of the house. We have several smaller girls as well. He "guards" his driveway at night with a pitchfork insisting people were walking on his roof etc. He has serious drug problems and sells prescription drugs all the time. The other day in a fit of paranoia, he fired a shotgun in his backyard to scare the boogymen away. My fiance who was home alone got scared and called police who came and arrested him only because he was found to have a prior warrent. They did not even confiscate the gun and he was home again the same afternoon! The moral of the story is the cops are not going to protect you. They show up after the fact and call the coroner. I went over and warned him to stay the **** out of our yard and warned him to stay away from the children. My fiance has her own shotgun and knows how to use it because again, the law will not protect you. Your neighbors sleep sometime so find out when that is and take the lawnmower out and let it sit there and run until it's out of gas. Blast your own stereo at these times. Shoot the damn dogs if they threaten you in your own yard! I'm serious. Also, your husband should grow some balls and protect his family! I'm sorry to say it.
