Security technologist: America making wrong choices

On this anniversary of the terror attacks, a recent Philadelphia International Airport incident that turned out to be a hoax gives pause to consider how airport and building security has evolved over the past 11 years.

Bruce Schneier, a security techologist and author of several books, inlcuding “Liars and Outliers,” told NewsWorks Tonight host Dave Heller, “A lot of the security measures I see at airports are what I call security theater — measures that might look good  but that don’t actually make you safer. I would certainly add shoe scanners and the full-body scanners and the liquid ban to that list.”

He said the problem is that these new measures came about in response to terrorist attempts — which are not likely to be used again. Instead he favors security techniques that don’t require authorities to guess the plot. Intillegence, investigation and emergency response can prevent attempts before they happen.
