I was watching the Hansen vs predator series.
In there a random guy called Chris Hansen goes online and pretends to be a 13 years old girl.
When people chat with him, he tries to steer the discussion on a sexual level ("I'm just coming out of the shower", etc.).
Then he lures them into his house, where there is a real life decoy (a 19 years old girl).
After some talking, the decoy goes away and Chris Hansen appears.
He then starts to question them, and he "let them go" out of the garage where the police arrests them.
They are charged with "criminal attempt to commit risk of injury to a minor".
My understanding is that Chris Hansen is a total random guy who does not work for the government. That is, he is not an undercover police agent.
Question: Is it a crime if I engage in sexual discourse with a random stranger that pretends to be a little girl, but he isn't?
I mean, he is not an undercover agent but a random guy who appears to do this for money/views or whatever.
