[Pistias]

Sounds like a psyop to me. I would think millivolt potentials from the brain and heart would be rather difficult to detect given the electronics in the airports and on the passengers, especially at a distance. Even if one could, what's the point? Measure heart rate and "brain activity?" Whoop dee do--a good attack wouldn't have nervous soldiers (and a mild sedative would probably be more than enough in case of expendable soldiers), and the false positives would be enormous given the worry over attacks and simple nerves.

Excessive low brain activity could also be detected. Don't let either on board. Fast or slow brain activity. People can take their air sickness pills after crossing the gate.
