JRF: Can't understand your comment. Security today is *significantly* better than it was before 9/11, *assuming* that the goal is to avoid passengers taking sharp objects (knives, box cutters, guns) in their carry-on luggage.
Now, I am a big critic of many things being done in the name of security. But, *assuming* that you think there is a need to avoid 9/11 type incidents (by that I mean to avoid people bringing sharp objects so that they can take control of the aircraft).
Are the methods being used excessive? I think so, but that is a personal opinion. One reason I think the methods are excessive is because the crew and passengers would not provide the same reaction (turn over control of the aircraft) after 9/11.
