Amanda, I think you handled the situation wisely. I do, however, agree with EZ2Luv's concern over the possible repercussions if you do decide to call the police in the future. It would be one thing if you actually lived with your Mom 24/7, but I think it could create a huge can of worms that she'd have to deal with on her own.
One thing I've discovered over the years, dealing with many, many different neighbors is that things escalate horribly when the police get involved. Years ago, I called the police on some noisy biker neighbors (they were Hell's Angels)...let's just say I learned my lesson on that one. I really do try to work out differences with neighbors these days, although to be honest, now that I live on my own acreage up in the mountains, I don't have very many problems anymore. Plus, my nearest neighbor used to be the county sheriff, so he keeps potential problems at bay for us. (I have felt sooo much safer since he and his family moved in.)
I bet it was the 16-year-old who spilled the garbage. He probably told you his parents weren't home because he was afraid his dad would suspect him...
