My question involves criminal law for the state of: WA
About a month ago I had some very sketchy folks move in below where I live. At first there was just one nice girl that moved in there and I introduced myself and everything seemed fine. About a week later, her boyfriend showed up and basically "moved in" (this is a 1 bedroom unit by the way) along with his friend. Ever since then, they have been extremely loud, come over to my place on three occasions asking if I knew where to buy Molly, Crack and Ecstasy. People have been coming and going all hours of the night as well. I called the police once already because I thought they may have been squatting in her house or broke in, because I hadn't seen her in days. The LEO told me that although these guys were a bunch of "gang bangers" and were very upset and crazy when the he showed up, that they weren't doing anything wrong. I was just making sure that the girl was okay because it seemed completely out-of-character for where we live.
Today, one of them was talking to a dealer outside in their fenced in patio. I sat my phone inside my house next to my open window and recorded a 7 minute long audio only conversation in regards to where Molly and something else was purchased. I don't believe I violated any laws - the recording device was in my house, and they were talking outside in the open where just about anyone could have heard them walking by.
My question I guess is what should I do at this point? Police or landlord? I'm not sure if I have damming evidence enough to go to the police, but my landlord would probably evict them immediately knowing that they have been conducting illegal activities on the premises (clearly against our lease agreement).
What would you do?
Thanks
