AIRPORT SCREENING: What TSA Is Doing. “Now, when TSA scrutinizes the passenger list, it won’t just be looking for known terrorist identities but also for fragmentary identities. So, if we know that a Nigerian is training for an attack and that his first name is Umar, we’ll select a lot of Nigerian Umars for screening. . . . Ironically, Europe is probably picking a bigger fight over reservation data with the Obama administration than it the one it had with the Bush administration. For the last administration, using travel reservation data was just one among a dozen or more counterterrorism initiatives, so a European attack on that initiative was just one more fight to preserve a piece of the last administration’s strategy. But for this administration, using intelligence to screen passengers is a signature, maybe the signature, counterterrorism initiative.”
