US | TSA Screeners Will Roam Airports, Test Random Fliers Portable detectors will take swabs from hands, luggage By Nick McMaster Posted Feb 17, 2010 4:58 PM CST Copied In this Jan. 4 file photo, TSA officer Robert Howard signals an airline passenger forward at a security check-point at Seattle-Tacoma International Airport, in SeaTac, Wash. (AP Photo/Elaine Thompson, file) TSA screeners will take a more proactive approach to finding explosives in airports under a new security program. Screeners will walk around airport gates and security lines with portable explosives detectors, taking swabs from random passengers' hands and luggage. The security agency first ran a test of the program after the attempted bombing on Christmas Day and plans to make it nationwide in a few weeks. "Had (Farouk) Abdulmutallab been subjected to a chemical inspection, there's a high probability it would have picked up the explosives," a RAND Corp. security analyst tells USA Today, explaining the reasoning behind the program. It will "create increasing uncertainty for the adversaries, which is always positive." Read These Next JD Vance in hot water over birthday boating trip.
