“Overreactions give people an incentive to become terrorists—not only by creating grievances but also by reducing the relative risks of turning to violence,” Northeastern University’s Max Abrahms, a professor of public policy, recently cautioned in Reason. “A standard assumption in political science is that terrorists are rational actors. Many people decide against becoming terrorists because they know that the costs to them will be severe. But if the government is going to treat innocent people like terrorists anyway, then no additional risk is incurred.”
