I can understand the inconsistencies we, as travelers, see from the TSA, however the public needs to understand that there are extremists from other countries are out to kill thousands of innocent U.S. individuals, just because we live here in the U.S..
These extreme groups don't just target the military, they target the innocent. In past wars, only those that wore the uniform of an opposing country would be targets. Now, it's a no-holes-barred. I am thankful that there haven't been any attacks over the U.S. soil, but this doesn't mean that the threat isn't there.
Many people try to say that the TSA isn't doing their jobs with these attempts, however, what these same people are forgetting, the "Shoe Bomber" and the "Underwear Bomber" originated OUTSIDE of the U.S.. Even British Airways boss rips the U.S. on our security (or lack of).
El Al security where they approach a passenger, is time-consuming, and is "racist": the profilers have a conversation with each passenger; as an Israeli Jew, they usually get the abbreviated treatment -- focusing more on where their bags have been since they packed them. As a foreigner, you get a much more in-depth grilling. As a Muslim? They want to know your shoe size, and then a whole 'nother screener comes over and asks you everything all over again, just to see that you keep your story straight. Like they say in the article above, the conversations they have are not so much about what you say as how you say it. The screeners are taught to iterate a few levels deep into your story and see that it doesn't break down under scrutiny.
'Total Recall'. In the movie, where passengers were going to Mars, passengers walk through an X-Ray passageway. This system should make airport security quicker and more effective. Another point to make, you keep your luggage with you and don't have to put it onto an x-ray belt.
Another item that the news media fail to inform the flying public, is that the TSA Body Image Scanners do NOT store images. I can understand how the news can be misleading, allowing viewers to believe that the images view are stored, and are capable of being sold to a Third Party then your 'image' is plastered all over the internet. This statement is simply FALSE.
