If Big Sis was as smart as she thinks she is, she should have insisted on better specifications for the airport scanners. The scanner should have been designed to be autonomous, capable of detecting explosives as well as metal objects, with the ability to differentiate between medical implants and prosthetics and guns and knives, all without human intervention. Humans get tired and lax, machines do not. We do have the technology.
