I went through this with a neighbor in a small California Town. I'm sure that this is more common than people know. Our Neighbor was a man who was always not home and his son a teenager in high school ran a drug business on our door step. We had some increasingly rough customers dealing drugs at all hours day and night.. The Police when called were belligerent to us and loudly yelled my full name and told the drug dealers that I was the one that called. My call to the chief of police did nothing. So, I decided to compile a list of all names, addresses and info on everyone in the police department that I had been talking to and the info on the neighbor. I called the DEA and left a full report on the anonymous tip line. Within a week the whole thing stopped, the neighbor moved to another state and the chief of police called me and personally explained. I'm not saying that this is the answer for everyone and I'm surprised personally that it worked at all. I normolly don't care what others do, and live and let live, but when you can't get out the front door without interrupting a drug deal, then it's an issue.
