Thank you for writing to Kerry. This is entirely not the answer to the problem of people attacking airplanes. The answer will not involve fancy machines with minimally-trained technicians, but no machines at all with highly trained specialists spending just a few minutes with each and every person getting on an airplane. Probably won't cost much more than what we currently spend on gadgets like pr0ntubes that are worse than useless and the money goes to people rather than corporations - win-win.
