Couldn’t find this anymore on YouTube, so I’m posting. I was working on Pearl Street the day it happened in the middle of all that black smoke. This impressive, well-researched video is almost twice as long as the heavily-edited Amazon version. If you have time, SEE BOTH – the Amazon one first. It’s significant what was deleted. A good follow-up is FRONTLINE “United States of Secrets” available on PBS, which documents post-9/11 changes in government policy regarding personal privacy.
