There is plenty of video out there, could a defmation suit be brought against members of the Black Caucus and Barney Fag? The videos clearly show who they are accusing.
I doubt if such a suit would succeed, but sure, they can sue for it. Basically anybody can sue anybody for most anything. Doesn’t mean you’ll win.
True story: somebody sued a car rental agency in southern CA because someone with an Irish surname rented a vehicle from the company, got drunk and ran into the plaintiff. The plaintiff sued the rental company under the theory that, because the patron had an Irish surname, the car rental company should have known he’d get drunk, drive and potentially injure someone. It was dismissed, but still, the car rental company had to mount and pay for a defense.
Sux!
