Don't try to oversmart yourself, it's obviously not working for you. I saw this many times.

The postman is only innocent if he's unaware of the illicit materials he's transporting. If he knows he's ferrying illicit materials, profits from it and encourages people on his route to give him illicit materials then he's no longer an innocent postman but a criminal. Could that sentence somehow be connected to the KWWH forum, Lifetalk?
