The FBI's "Preventing Violent Extremism in Schools" program is based on invalid concepts of how people are radicalized. The guidelines criminalize free speech critical of the government, and use normal teenage behavior (distrust of authority) as markers of extremism. This is an unconstitutional overreach of authority by the FBI.
