how right you are jrd...
I fly to Atlanta about five times yearly...thanks to a generous son in law...and the tsa is totally illiterate, I am bilateral cochlear implants and the tsa didn't even understand what I was telling them about my head area and that I've been medically advised not to go through scanners, they said they are safe for everyone and just go through!!! I had an ID card that I put in their face and said I would take a physicians advice FIRST...
personally I feel they are just too damn lazy to get off the over sized stool they put their fat a$$ on...
I find that the worst airport to go through...very dark.
