Thanks, for the comments. I will provide this to my wife. Her paper is an opinion piece.
My opinion on this subject, is sure there are conspiracies. However the ones in the same category of 911 are not plausible. It is the same argument I've made in the past. Too many people would be involved for it not to be exposed.
The eye witnesses that saw the plane crash into the pentagon are to be dismissed? The same with all the other various conspiracies that require 100's of people if not 1000s to cover it up.
BTW you don't need 911 to get the government to spend billions in the military. T
