Chris Hansen, government snitch?

I'm sure most of you have heard about Chris Hansen's pet project, "To Catch A Predator". Don't get me wrong, I think what Chris is doing is important work. I don't even mind him going to Congress to testify. I may disagree with him, I may think he's getting a little bit too self-righteous, but that's not the point.
What the point is is that Chris is now working with government agents in pursuing his cases. You've seen it, guys get into the house, hoping to get it on with an underage person, and then after an embarassing interview, are then out on the street when the police make an arrest. The original shows were not done with police cooperation, but now, they are.
Does anybody else find this a bit disturbing. The press, the guardians of an independent voice, working hand in hand with the government to catch predators. One gets the indictments, the other gets an Emmy. And how can NBC then call a halt to these little cooperative exercises with the government? A lot of you say, "but John, these are child molesters." Okay, they may be down on the evolutionary scale, but who they are targeting is not the point. Imagine NBC and the cops going into cooperation on interrogations, or on other stings?
I may be the only voice criticizing Chris Hansen about this, but I am. I'm not criticizing what he's doing, I'm criticizing him sitting out there with a bunch of cops. He's acting as an instrument of the police, and that is tainting his program. Of course, I probably am the only one to see the journalistic ethical questions involved with this, but there are serious issues that Chris needs to take into consideration.
And oh yeah, I don't go for pre-pubescent girls, period (or lack of it...awwscrewit, you know what I mean).
