Texas DA Louis Conradt's suicide probably did get the show cancelled. There are actually people who were trying to help predators by complaining about the show. Conradt's suicide while the SWAT team was serving a warrant for his own pedophile activities was the straw that broke the camel's back for the To Catch A Predator show. He committed suicide with the SWAT team outside most likely because he knew he was guilty and preferred sending folks to jail rather than going himself. If he was innocent, why not have his day in court like everyone else?
However, if the many other innocent until proven guilty types on the show were not pedophiles, they would not have come onto the radar screen of the show as such. If you have no interest in young girls or boys, you would not carry on with them in any way shape or form, online or off. I like the show and while I've only seen the re-runs on CNBC, I hope the show does make a comeback.
