TSA's really in a no-win situation today.
They've chosen to back off and let things run really smoothly - which I think was their best choice - assuming there were a bunch of travelers.
But since the travelers didn't show up - letting things run smoothly is a disaster for them - it highlights the fact that nobody is flying.
Now if they had taken the "hard azz" approach and backed everybody up, then the public might be angry with the opt outs, but the publicity would destroy them in the long run.
Lose lose for TSA. The writing is really on the wall now. They better go to plan B.
