So...I bought a house in a nice quite neighborhood about 3 years ago...all the neighbors were cool. There's a rental house across the street, and the tenants at the time were cool. Then some asshat bought the place from the previous owner, raised the rent about $500/month, the old tenants left and this family of dipshits moved in. Right now, I'm looking out the window 3 cars on the street with for sale signs in the windows, there's a POS mustang in the driveway with the alarm going off, my windows are rattling from the bass from the stereo in his POS lincoln on hydraulics that he's jumping around in his front yard. I'm getting tired of it. I've called their landlord...but he doesn't seem to give a shit so long as they're paying the rent. I called the cops earlier when much of the same was going on, but by the time they showed up, all the assholes had left somewhere and all was quiet. Short of pipe bombs, how do I solve this problem?
