I have advocated on this forum the screening of passengers about to board planes by their fellow passengers. Have all passengers assemble at the gate 30 minutes before fight time with name tags on and ask them to mingle and talk to each other for 5 minutes. Passengers could then write down the name of any other passenger they think needs more thorough screening.
Much more effective and efficient than the stupid x-rays and body groping they now do.
I can pretty much guarantee the underwear bomber and shoe bomber would have been identified by this method, as well as the 9-11 teams. People have a sixth sense when people are up to no good - by there behavior even more than their appearance in a photograph.
Yes!
And make the process into TV show. Would beat out “Survivor” :).
