I didn't jump on this at first because in part it wasn't clear where exactly it was on the continuum between creepy and criminal. And reading this latest from ABC it's still not clear to me. I believe the age of consent in DC 16 - is it illegal to "solicit sex" over the internet from an underage person even if that person is of age in their respective state? That's rather odd.
Don't misunderstand, I'm not defending Foley's behavior, I'm just curious about what makes it rise to the level of criminal.
