We had a long and heated discussion on the morality of this TV show awhile back. Here is the latest: a court has ruled that NBC can be sued over the suicide of a former Texas prosecutor who committed suicide after he was caught by the show trying to hook up with a 13-year-old boy. The court agreed that there is merit to the lawsuit:

Rather than merely report on law enforcement's efforts to combat crime, NBC purportedly instigated and then placed itself squarely in the middle of a police operation, pushing the police to engage in tactics that were unnecessary and unwise, solely to generate more dramatic footage for a television show.

This doesn't mean that the court agrees with the suit, just that the legal action is allowed to proceed and won't be thrown out of court.

Nobody living can ever stop me
As I go walking my freedom highway.
Nobody living can make me turn back:
This land was made for you and me.
