We've talked about this before.
I have a huge problem with security screening passengers who have completed their trip and are not flying again on the same day.
This is the case in passengers arriving in Atlanta, Cincinnati, Cleveland, and some other airports. The customs and immigration area is contained in a remote location. Passengers must pass through a sterile area to get outside of the terminal. So passengers have to be rescreened after clearing customs--even though they're only headed outside to cars and ground transportation.
On one occasion, I arrived at CVG after a long flight from Paris. I had to wait 30-45 minutes in line, take off my shoes, have my stuff swabbed, etc. even though I was done flying for the day. I was too tired to resist but I desperately wanted to refuse screening and say, "Just let me go home!"
To my knowledge, the TSA and Airport Authorities have taken no action to correct the poor planning at these airports. It seems particularly expensive and time-consuming to screen all of these people who are merely leaving the airport. I'm surprised others have not attempted to refuse screening.
