And it's amazing that such cheap and low-tech methods brought down how many four buildings, killed almost 3000, hit the center of our Defense Department, shut down aviation for a few days, shut down portions of our economy, and caused chaos with a flood of new security measures. Who's counting courage when the methods were just as deadly as a massive attack by the Japanese Navy at Pearl Harbor. You have 19 guys with box cutters that did what no one else has done in our history. While you make their methods seem trivial I think it is a testament to their resolve and the thinking they put into this to make the human mind and body more deadly than missiles, aircraft carriers, or massive armies.
