That statement is technically correct but fundamentally nonsensical. Yes, secondary screening is based on the passenger's "behavior" (rather than racial or ethnic characteristics), but such behavior has absolutely no connection to terrorism or even to more mundane criminality. Do you believe that suicidal terrorists buy one-way tickets because they're going to die and don't need to return? I don't believe that the 9/11/01 hijackers bought one-way tickets. Using the type of ticket as an indicator of terrorist tendencies is about as reliable as the color of your car -- which is also a "behavior."
