Reality T.V. when its not scripted...

Some post back I already talked about reality T.V. a little and how most of them are scripted. But some are actually real. For example: "First 48" which is a homicide detective show that takes you through the crime and eventually a confession from the criminal. The show makes the faces of people in suspect fuzzy but the one who is guilty is fully shown. The producers have to get permission from the victims family to allow them to appear on the show but apparently the criminal has no say in the editing. It makes me wonder if it's exploiting the criminal? Although I feel pretty strongly that a person who can take a life in front of G-d basically disowns any rights they have on privacy laws.
