While flying through San Diego a few weeks ago I noticed that TSA has re-added an effective layer of security – the random screening of individuals as they board an aircraft.
This process was initially implemented after 9/11 and is commonplace in Europe. It was eliminated as part of a so called “silly rules” reduction several years ago. However, this process does provide an additional layer of security to screening as screening is still an imperfect process, and also helps deter employees with airport access from passing a prohibited item to a passenger.
