You seemed to be referring to some amazing bold look into the events which most people are not aware of. I will just have to assume that the "truther" stuff Warb mentioned is the sort of thing you are referring to, in which case, I have already heard all the arguments. If I google search it myself, all I will find are the likes of Rosie O'Donnell shouting about how "fire doesn't melt steel", which made her sound even more ridiculous than the poor woman usually did.

When doing research, documentaries are the absolute worse way to find information. They are always a bunch of smoke and mirrors providing half truths in order to make their point to their viewers. It is essentially listening to a single voice for a duration, and being asked to take your stance based on that. Even the opponents of the idea that may appear in a fair and balanced documentary are at the mercy of the editor for their words to show through in the manner they intended them to be heard when they spoke them. Not to mention, you linked to a TV show that also exposed government UFO cover ups. Makes it hard to take seriously. Not to say I don't agree with somethings said about the national banks, but I think a lot of people take it to comedic proportions.
