This is definately a topic with a double edged sword. For all the good they are trying to do to make the public very in your face aware of the undeniable dangers, they are still going about it the wrong way. Lets face it, we are very aware that sexual predators exist both online and in the streets, but how often do we really consider just how common and real it really is. Most of us are at a safe age where this would not be a particular problem. True we are still at the mercy of other online dangers. Unless you actually know the person on the other end if the computer, you can't be 100% sure who you are talking to. For example sociopaths, and serial killers come in all shape sizes and ages and they target ages of all kinds. But not to get to off topic...As for these primetime show, I don't think its intent was to entertain, but many of us tune in and get our jollies at the expense of some guys intent to do bad things. That is where the fine line lies, "intent". The show's "Intent" was to inform and hopefuly make aware to the public and other predators the serious nature of the crime. Unfortunately by using intrapment it gives cause to question the legal limits in which they can truely prosecute. The biggest thing that is being made clear is that these sickos are willingly seeking out and acting with criminal "intent" despite the fact that they don't know that the girl is really not a minor. They think she is and they are going for it. Maybe due to the factors of it being a set up and he actually did nothing wrong the guy goes free but hopefuly he will think twice before doing it again. Best case scenerio is that the guy learns a lesson and gets help for his problems and never does it again. Another thing is that hopefuly parents will be more aware and take better action to supervise and inform their children of these online dangers. Both sides of the story stand to learn a serious lesson.
As for it being a public display of some guys total humiliation, I think he got what he deserves. Yeah its going to ruin his reputation, but had that been an actual kid, just think how it would have ruined her self image and psyche.
My opinion on whether or not it is entertaining is borderline. I don't think it was intended to be, but I believe entertainment is subject to perception.
