From Alternet:
In the ten years following 9/11, the FBI and the Justice Department indicted and convicted more than 150 people following sting operations involving alleged connections to international terrorism. Few of these defendants had any connection to terrorists, evidence showed, and those who did have connections, however tangential, never had the capacity to launch attacks on their own. In fact, of the more than 150 terrorism sting operation defendants, an FBI informant not only led one of every three terrorist plots, but also provided all the necessary weapons, money, and transportation.
