People standing across the street on the corners early morning into the night. Going into a boarded up house. Been watching it for the last year. Won't report it since it's several blocks away from me. As well as knowing that Baltimore PD is good at sitting and watching this shit, not actually busting them. They literally sit in front of a corner store that is a front for trafficking but seem to enjoy just watching the show. So yah if you can somehow get the right peoples attention that might be a start.
