Truth does not matter. The U.S. demolished WTC 1, 2 and 7, blaming it on ragheads that supposedly flew 2 planes towards WTC 1 and 2. (Note that the number of buildings demolished exceeds the number of planes by 1.) As a consequence, billions of security searches are now conducted throughout the world annually, with the main goal of conditioning people to accept ridiculous and unfounded orders as a part of their job, and ridiculous and unfounded procedures as a condition of exercising a very basic human right - to travel around the world. (And this was just an example, the real atrocities are found in other parts of Patriot Act, nicely prepared before the event.)
