This is indeed true.
Several people made many billions of dollars off the 9/11 attacks.
Tens of thousands of freedoms Americans had were stripped away via the 'patriot act' along with other bills and executive orders passed.
Governments have always used false flag operations in order to gain more power over their people, justify an invasion of other countries and to generate huge profits.
Just like with Nazi Germany, Hitler burned the Reichstag down and blamed it on communists in order to turn Germany into an absolute dictatorship. Stalin in the soviet union did something quite similar to this, though I can't remember what it was at the moment.
NEVER EVER EVER trust governments. They always lie to the people.
Government is really just an illusion, just a small group of people which seeks to dominate the masses of people.
Anyone who wants to dictate and control another person's life (politicians, etc...) are sociopaths.
