I'm sure I'll regret posting this, but here it goes.
I won't rush to judge the accused. There have been stories about similar sting operations where the "young girl" said she was of age. As the accused is on the way to see her, she informs him that she is underage. He either does not believe her or thinks she is now role playing, so continues to go be with her. It's things like this that has caused many of those cases to to dropped.
I would like to hear some of these stories. I haven't heard of any actual law enforcement agency stings employing this kind of bait-and-switch entrapment.
