Actually this is not just "some" evidence that is here. There were way too many coincidences that happened that day or the days prior to 9/11. Mathematically it is impossible. If you think about it, this 'terrorist fight' hasn't yielded any results so far, but with it, they have justification for spying on the population.
Very true. Actually, the Patriot Act as a whole was a huge hit (not in a good way) on our civil liberties and basic freedoms. Most people are just too oblivious to it as long as they get the constant "feel good" stream of crap from the media and are totally absorbed in the latest from the music and gaming industries to the point of not knowing or not caring what is actually going on in the world around them. Seems people these days are more interested in the latest app, Facebook post or Tweet to really care about important things.
The Patriot Act is the biggest piece of evidence in my opinion that something shady went on. It just gets passed a month or so after 9/11 without a peep and that was the beginning of the end of our liberties. Terrorism is always used to scare people into believing they're under threat and to protect everyone we need to spy on everyone in the process.
