Would agree they are pretty hokey, but your comment has one big flaw: CBS fell for it. They were obviously good enough forgeries to trick CBS, so they weren't so bad that it had to be a plant.
I think CBS (Rather) is obsessed to the point that they barely checked on the documents AT ALL. Their arogance and ignorance blinded them to what would happen when the fakes were exposed. They didn't think talk radio, FOX News, etc. would report on the fakes without absolute proof they were fake, and didn't count on FR and the bloggers being so persistent.
What did Hitlery have to lose? If CBS didn't use them, oh well, on to the next "destroy Kerry" plan.
