Although it never mentions how young the sherrif's were saying their were...I guess I have to assume that they were below legal age.
Frankly, I could care less if men do this online, cyberspace is nothing but fantasy. However, I guess anyone who takes it into the real world is an idiot. You often wonder when you get those IM's that say "Hi, watcha doing...15/F/Oklahoma City" are police looking for entrapment.
Is this illegal? If you just chatted like a horny bastard online but didn't take it into the real world? You think you could get in trouble for being really raunchy and nasty to "15 year old girls" only online?
