kvenlander has it exactly right. The human interface features are designed specifically to be inconvenient and degrading. It's all about asserting the feudal sovereignty of the Heimatsicherheitsdienst over the rest of us.
Or perhaps I'm just jaundiced by my last-but-one trip through airport security. Like the obedient serf that I am, I carefully placed all the metallic articles that are normally about my person - watch, rings, phone, coins, wallet, keys - in a little plastic bag that I had in my backpack for the purpose, and stowed them in the pack, which I placed on the conveyor. I removed jacket, shoes, hat, and sweater and placed them on the conveyor as well. I removed the computer from the backpack, placed it in a separate bin, placed that on the conveyor. I walked slowly through the metal detector, which went BEEEP!. Officer ordered me to remove my belt and eyeglasses, place them in a bin, and go through the detector again. (Now I am effectively blind - I am legally blind without correction.) BEEEP. Officer wands me, finds nothing, and orders me to another line for the "puffer", still without my glasses or belt or personal items, which are still in the X-ray. After 15 minutes in line, I get "puffed", return to the original checkpoint, and find that my pack is "suspicious" because of the length of time that it's been "abandoned" there. Officer decides to do a manual search, and unceremoniously unzips the backpack and dumps its contents (some of the articles are fragile) on a table. Officer yells at me when I attempt to prevent a couple of
[what I think are - I'm still without my glasses] pill bottles from rolling onto the floor ("STOP! You can't touch that!") After a few minutes of finding no contraband, the officer barks at me, "Well, you can't stand here! Pick up your things and move along!" I ask for assistance in finding my glasses, and the officer simply says, "MOVE!" (Fortunately, the old lady who is now behind me spots them and points them out to me.) I get my spectacles on, and try to pick up small articles and cram them back into the backpack. The officer rests his hand on the holster of his gun and barks "Get OUT of here! NOW!"). I grab outer clothing, backpack, shoes and computer, sweep what small articles I can onto my jacket and bundle them up, and leave, sans belt, having abandoned various bits and pieces, including one of my prescription medicines at the table.
From behind me I hear a fellow passenger loudly saying to his companion, "people like HIM shouldn't be allowed to fly!"
I suppose that in this era of terrorism, it's no longer reasonable to have any idea why someone in uniform is threatening you with deadly force. At that point, I believed that I was abandoning my property to save my life. Since the security screener was accuser, judge, jury and executioner all rolled into one, I had no idea what I'd done wrong.
But in our post-9/11 world, that's the price we have to bear for our safety. I'm sure that the screener was just doing his job, and that there was some obscure failure in my understanding or preparedness that triggered the problem. The screeners are only there to protect us and they know better than we do. And we can't be allowed to know how they make their judgments, because that will just play into the hands of the terrorists. Anyone who says otherwise is a traitor who deserves summary execution. And don't raise any liberal nonsense about a "fair trial" - that right belongs only to citizens and anyone who's a traitor has renounced his citizenship. God bless the USA!
