Thanks for the information
Bart, thanks for your informative response both to the questions raised here and mine about quality control, etc.
It seems to me that all of us should carry copies of TSA policies as well as Bart's posts on how to handle problems with us at all times. As if we need to drag anything else along, but they could come in handy someday.
I do have another mostly rhetroical question: Does anybody at DHS/TSA get that these screenings procedures are not making us any safer?
I'm assuming the answer is: Yes there have been individuals at DHS/TSA who understand what a farce this all is, but they are no longer employed at that agency.
