I agree with O'Reilly about the ACLU files....I'd love to have a good look at those and agree they should be released. As well as groups like Greenpeace, left wing radicals, right wing radicals...let it all come out. I know, however, that whatever papers the ACLU gets, they will hold all those very close to the vest, not allowing the general public any disclosure. If they do, through website files, I'm very sure the material will be heavily edited, if not a complitation based upon several different documents edited to appear as one specific document. Though I know they'd never ever never stoop to that level of deception. Not a pack of ultraliberal lawyers. Nope.
And why shouldn't the FBI and CIA have files on all these groups? Someone gets picked up, drops a name or group, and it gets put in a file. Someone turns evidence and implicates others to deflect personal blame, and it gets put in the files. Those things add up, especially with a group as visible and controversial as the ACLU, since many of their lawyers have represented, pro bono, the worst felons out there. In case any forget, the FBI investigates felons. Yanno, like ecoterrorism (tree spiking, arson activity in housing developments), riots and violent threats and/or activity against other groups, pedophiliatic stalker groups (NAMBLA), domestic terrorism (including militias, hate groups, bomb makers). The FBI is just doing their job: investigating.
