When John Booker was released from mental hospital, two unofficial FBI agents began luring him into a fantasy terror plot.

It is legitimate for the FBI to keep tabs on mentally ill people who show an interest in terrorism. A few of them might proceed to real terrorism. It is also legitimate for the FBI to run people in terrorist circles to find out about real terrorist plans.

However, when the FBI lures Americans into fantasy plots, who would never have done anything on their own, it does nothing but harm.
