There is a strong rumor that once TSA rolls out the protection for the Metra trains, they will focus on the CTA elevated train and subways, then buses, limos, and taxicabs. Soon, I suppose, private autos, bicycles, and children's trikes and wagons will come under TSA scrutiny. Pedestrians will have to travel in the nude to demonstrate they are not carrying IEDs or WMDs!
I'm no longer sure whether this is
or a logical conclusion based on "mission creep" precedents of the U.S. Government!
