Yeah, I remember before 9/11 flying from seattle to vegas and back. My friend had a duct taped cell phone that really looked like a bomb, as well as a pocket full of keys, etc... walked right through with no problems. Needless to say we didnt exactly feel safe on that flight.
Next plane I took after 9/11 it was much different, they made me take of my shoes and pat me down. Frankly it looked like th guy doing the pat down wasnt enjoying it anymore than I was, but I still felt safer knowing that at least something was being done.
As for the full body scans, I would prefer those over the pat downs, considering it helps move airport traffick along faster and safer, I dont mind if there are some blurry black and whites of me out there. Of the 1000's of people subjected to these searches every day, I am just another person not carrying a gun and am confident I am of no interest. even knowing the pictures where semi-detailed like the links above, I am not that worried about it.
