The real question remains “Why at all?” and the status of these would-be murderers as privileged post-graduates debunks the usual Lefty nostrums about terrorism arising inexorably from the poverty, oppression and “disenfranchisement” of the globe’s Darwinian short-bus. The answer lies more plainly in a memorable line of a memorable character. In 1971’s “Dirty Harry” the city of San Francisco is being terrorized by the rampant Scorpio serial killer. Clint Eastwood is in classic formulaic dialogue with the big shots down at City Hall who just don't understand what they’re dealing with. Eastwood says “You're crazy if you think you've heard the last of this guy. He's gonna kill again” and the archetypal skeptical D.A. character responds “How do you know?” (A little imagination here to invoke the Eastwood signature voice enhances the flavor of the closing fastball). “Because he likes it” answers Dirty Harry.
