The best part is that they dress up the girls in super tight hot pants and stuff. Good show.
Had the man not been possessing the lubricant, they couldn't have charged him with anything. This is because the transcripts of the chat do show that she goaded him into coming and coerced him to come. Despite the fact they call the police and the man is arrested afterwards, it's entrapment, as they are working in tandem with law enforcement. But had he not had that lubricant, he could've sued for entrapment.
