UI Air Security Expert: More Searches are Not Equal to More Security
Airline passengers are putting up with a new and often unwelcome level of security screenings, but a University of Illinois professor who studies aviation security said those searches may not be useful.
Thanksgiving-weekend travelers at the nation's largest airports reported few slowdowns or other problems with "backscanner" machines that give screeners revealing images of passengers. Those who turned down the scans are subject to intensive pat-downs.
Professor Sheldon Jacobson said he believes federal officials pay too much attention to searching for banned items, and that the high-level searches should not be the first line of defense against terrorists.
"The question is, is this an effective use of a very powerful technology? In our own research, we don't believe it is," Jacobson said. "We believe that using it for secondary screening is far more appropriate and will actually facilitate a far more secure system, which is very counter-intuitive in some sense."
Jacobson says more effective security should focus on a passenger's intent. He said the Transportation Security Administration needs to further its research on ways of filtering out passengers based on background checks and looking for behavioral red flags at the airport.
