those shows are all fake. i work in the industry and know.
the only one that is real is 'COPS'.
my experience with 'hardcore pawn' is that a production assistant thought of the whole scenario for my brother and family. it went like this.
since he had a camera to take photos of him & family with the stars of the show, she suggested that he was there to sell the camera because the had no money to get back to Georgia, then argue about the price and get kicked out of the store causing my niece and nephew cry about how they were man-handling their dad.
quite funny, but all staged.
take it for what it is.
