Something that has always bothered me
In the first couple of investigations, the men would just leave after their confrontation with Chris and would sometimes be charged and arrested later on for what they did. After those, they decided to create sting operations so that the men would be arrested immediately after leaving the house.
I do hate these predators a lot but, it's always bothered me whenever the prdator asks Chris if he's under arrest or is going to be arrested, and Chris just says something like "that's not up to me", and then when he's done with the interview, he tells the mean that they're "free" to go. That obviously creates the impression that they won't be arrested and are literally free to go, only to have them barely get through the door before having the police ambush them.
Why couldn't Chris let them know that they were going to be arrested? They obviously aren't under arrest while Chris is talking to them but, they will be very shortly so, why not say so.
