I watched several episodes, not many, and I assumed that the format was always the same, that they waited for the child molester to show up at the staged house.
As many others have pointed out, this was not the case in at least one instance, where they went to the home of the person involved.
That’s different. That’s a horse of a different color.
They met another guy in a park because he refused to go to the house. He turned out to have a record. The idiot suspected it was a set-up and showed up anyway. Sheesh...
If you have a DA who is doing this stuff, it’s best to get that out in the open. Imagine the damage a blackmailer could do.
