So live-in and I were trying to figure out how they even film the show (how are they not caught with the same camera crew following them around that are following the law enforcement folks around?). What it seems like is that the moonshiner's contracts are different than those of law enforcement. The law enforcement part is shot fairly recently, but some of the moonshiner footage is several years old.
