A lot of people made a lot of money from 9/11. A lot of people who had stolen a lot of money got a "get out of jail free" card thanks to 9/11. The total adds up to trillions - and that's when a trillion dollars was a lot of money. For example, take the "missing" money from the Pentagon. The most recent estimate (2013) is that $8.5 trillion is missing and that's just from the Pentagon.

FBI -- WHERE ARE YOU?!!!
