So you believe only the Americans do this and no other country does it? Not that it makes it right, but this practice is not unique to the USA nor just to the TSA. This happened even before the TSA existed.
If you are trying to claim that Europe and most of the rest of world has airport "security" with the iron fist & draconian regime of the USA and their TSA then you are wrong on almost every level.
Remember the US isn't the only country which has issues with terrorists and for most of us hasnt resulted in giving up all our civil liberties and privacy up like your good selves.
Let's take this a step at a time.
Apparently your claim is that the rest of the world does not have "security" with iron fist & draconian regime of the US. So let me knock this claim down. First as background information. I personally have traveled through at least three dozen airports in the rest of the world over the last two decades. Second I work on international standards committees, where I frequently meet with and discuss such issues over a beer and such with colleagues who travel even more widely that I do. So all in all I would say that I have good working knowledge of what happens at around a hundred airports outside the US.
Now then.... Just to give a few examples about how non-strict and non-draconian security is at airports outside the US:
1. Milan Malpensa last week, a colleague was accosted at gunpoint on the security line at the check point for no known reason. I will point out that no one at the US security check point has ever pulled out a semi-automatic rifle to my knowledge.
2. In Israel, at Ben Gurion, if you have been to the West bank for any reason during your visit, you are more than likely to get special attention at exit security, which on occasion goes so far as a strip search in a private room because strip means strip.
3. Delhi IGI, everyone gets a free massage (i.e. gets thoroughly patted down) irrespective of what the metal detector says or not. Often, there is a second search of hand baggage at the boarding gate.
4. At Berlin Tegel I got patted down thoroughly even after passing through the metal detector clean, and then was hauled off to a special room to riffle through my hand baggage which had exactly six items in it - a laptop, its power pack and mouse, a book and my car and home keys. The guy wrote down by hand in a fat notebook, the complete inventory of those three items, plus the two items from the tray - my cell phone and my wallet - for what purpose I don't know.
5. At Heathrow - they decided that my hand bag had too many things in it for their X-Ray to work properly and so proceeded to dump the contents on a table and look through the 7 items that were in it.
6. The day I passed through Frankfurt Rhine-Main last year, inconveniently, for some unknown reason they could not use their baggage X-Ray machines, so lines ran out the door to the next terminal (along the inter-terminal transfer passage), while they hand searched everything, and people who had connections shorter than three hours or so - many missed their connections. I had a longer connection so made it.
I can go on and on .... to show that the security checkpoint almost anywhere in the world are invasive of privacy, sometimes totally silly and yet are driven by the perceived level of threat at that point in time. I am actually OK within some reasonable limits with that since I believe air travel is a privilege and those that partake in it are doing so voluntarily knowing of the potential dangers and potential for loss of privacy to guard against same.
I believe that in participating in any collective act one chooses to give up certain limited set of freedoms and rights in exchange for the value returned. So the whole oh so holy attitude of "I will never give up...." is just plain silly. Specially if you are married for example, already of your free choice you have given up a whole heck of a lot. You understand that is the price for which you get a life partner. Similarly you pay a price in freedoms when you fly. The Choice is for each to make, and no one does not have to fly if one does not want to.
But my original point was that this loss of privacy and freedom is not specific to the US. It is a worldwide phenomenon, and I will add that in many other places it is substantially more intimidating than in the US, and overt racial profiling is much more prevalent outside the US than in the US. Indeed in the US these days with TSA-Pre, it is often a considerably quicker and less unpleasant experience than in many other parts of the world.
If needed I can document many more personal experiences and those of friends to further establish my claim that airport security of varying levels of unpleasantness is a worldwide phenomenon today and has been from even before 9/11.
Your turn... to provide specifics instead of general invalid statements.
