Not to defend their approach, but... The chatbot could be used to harmlessly engage with people in chatrooms, and flag 'grooming behaviour'. Then, those conversations could be stepped into by an actual person - saving having actual people monitoring the chatroom full time. The police move in when the IRL meeting takes place, and the suspected paedophile arrives full of evil intentions - at which point, the police have plenty of profiling experience and the guy probably takes a plea. So the chatbot is more about whittling down the suspicious participant list, without soaking up police time.
