You folks aren't getting it. CREW knew it wasn't a crime, and if they'd given the FBI the original emails or even copies of them, the FBI would have said, "Yeah, creepy, but no crime here. Move along folks, nothing to see." That's not what CREW wanted, so they gave the FBI something they couldn't actually act on - the edited versions. That allowed CREW and the rats to maintain the contact with the FBI over it and to keep it alive at the FBI so when they broke the story, the FBI would already be involved in investigating Foley or at least it would appear that way. To be able to have the media saying Foley and other GOPers were under investigation was a big bonus for them.
Well if CREW was hinting at the FBI that there was a crime when they jolly well knew there wasn't, that should bring some blowback.
