From a law enforcement stand point, this happens quite often. There a few departments in the area here that have detectives that do the same thing the TV station did... on a daily basis.
Ive been lucky enough to read some of the conversations from the predator to the "victim" as well. These sickos really make an attempt to try and get with these underage victims. I will admit, its quite funny to here some of the SWAT raid stories though I watched Westerville PD arrest a sexual pred. about 6 months ago, the guy defintely looked as if he never gotten any in his life hah, but luckily now, he will get some from Thunder Dick in the federal pound me in the ass prison
