While he has made a few goofs (honest mistakes, I believe), he documents and sources his information quite well. I'm curious why you think he's a liar.
I’m not saying he’s a “liar”, per se. He’s a showman. I don’t blame a showman for being a showman. Someone else on this thread asked me if I realize what Beck does, and they had a point, but all the same, please don’t pee down my back and tell me it’s raining.
