Actually TSA has more to do with imposing even more federal authority in airports. From here they go to Greyhound and Amtrak and from there to the local metro transits...and from there to our highways.
Get ready for a federal authority with a radar gun on the interstate "scanning for terrorists." For us in Atlanta that means in the corridor between the north 120 loop on I75 and I285 we will have Cobb county sheriff, Marietta City police, Georgia State patrol, and soon a federal agent on patrol all competing to issue citations.
All you snowbirds headed for Florida should take note of this corridor. It's a major income source for three agencies at present. And if my prediction of incremental progression is correct, soon to be four.
