These exchanges come from the doc http://www.viddler.com/v/588d3813The Paedophile Hunter, which aired last week in the UK. The doc profiled Stinson Hunter, a vigilante in the UK whose goal is to catch child predators. Hunter and his team set up dating site accounts belonging to decoy underage girls to lure in the creeps, and then when they show up to meet the girls, they're instead surprised by Hunter's camera crew. The footage of Hunter's sting operations is then posted online. It's very lo-fi To Catch a Predator.
The men are fucking disgusting. Here's one of Stinton's gets:
This sort of independent vigilante work is seen as a problem by officials, who commented in the doc. Basically, Hunter ends up with a ton of evidence in his hands that must be handled with care. Still, an interviewed lawyer says that Hunter is not doing anything illegal.
The doc reports that his efforts have led to the conviction of 10 predators. Stinton thinks that's too low an estimate. The popularity of The Paedophile Hunter helped Hunter raise almost £30,000 on Kickstarter to expand his operation.
