I wonder how any reasonable reporter, hell even ones with giant biases, could go with anything Bill Burkett handed them.
Burkett had a well known grudge against Bush and was unstable as any of them could see.
I would not be at all suprised if Burkett himself made the "documents" himself and sent Rigler and everyone else on a snipe hunt. That is an explanation that fits the facts better than these vaporus "leads" he gave them.
I am comming to the conclusion that these CBS reporters are every bit as stupid as they are biased.
If I were investigating this, Burkett would be the prime suspect. He is both obsessed with Bush and demonstratively unstable enough to have fabricated the documents without considering the consequences.
