Ok, a couple of things. First. I agree, this, much like your example of TSA routine, will be focused primary on law abiding types. Those that these systems are supposed to weed out will not bear the brunt of this intrusion, should it go in to widespread application.
Second. Having some experience with law enforcement, I know driving without a license does not automatically equal arrest, far from it.
Third. I was born and raised in Kansas.
It was a nice place during the late 50s when I was in Wichita for four years flying and instructing in B-47s at McConnell AFB and Salina.
