It's quite funny how John doesn't actually argue with any of the factual points given in the popular mechanics article, and instead refers to people here being 'ignorant'. Attacking a persons character, such as Benjamin Chertoff, doesn't debunk his argument. Listen to what's being said, not who's saying it. If we all adopted this approach, people would not take what you have to say in most technical discussions seriously, since a lot of the time people don't take your conspiracy theories seriously.
