Actually this is one of the things I thought the BBC documentary contributed most with. If you read the name of a military airline pilot or a scientist on the net, its very easy starting to accuse them for being "in on it" or "neocon" or "bought". However if you get to see the person behind the name tag its a totally different story - seeing the C-130 pilot, O'Brien, in the living, the coroner, Miller, and that scientist doing the Pentagon simulations, Hoffmann - suddenly they are not just "lieutenant colonel" (obvious government secret agent), but next-door neighbour, father-of-two, O'Brien (I wonder if Fetzer would be as feisty towards O'Brien had he been face to face with him...). BBC did what should be considered 101 - they left the internet and went into the real world and talked to the sources.
Its very, very easy sitting behind a keyboard in your own room, dissemniating accusations, playing detective, investigator or scientist. Its much harder to do it face-to-face. Me thinks it would have done the world a lot of good if all truthers had to actually face those they accuse, before posting on Youtube, Google and in the LC forums...
