The difficulty is that he wasn't directly involved in the situation as far as I saw, it was just insinuated based on the context. I really have no proof whatsoever that he did anything illegal. The organization I work with generally tries to avoid calling the authorities because oftentimes the victims get criminalized instead of the johns or pimps. We primarily just direct the victims to safe places and services. Anyway, the only reason I was considering going to his family or friends first was because they may have more information to offer about the situation that would further incriminate him. If I have enough to go off of, I'd consider reporting him.
