5050, lets take another example then: Taking your shoes off at the airport. Do you really think that improves security in any meaningfull fashion?

I know we spend alot of time and money. I also know most of the measures in place are mere theatre. People need to learn to be less scared, and we need to spend our time and money more sensibly.

The reason there hasnt been another 9/11 style hijacking is because the terrorists now know that we know what theyre up to. They know that if they try and hijack another plane with boxcutters, we are all going to rise up and beat the shit out of them and crash the plane if necesarry.

It certainly has 0 to do with removing our shoes, or "no-fly" lists, or secret "terror rating" scores accumulated
in secret, or mass investigations of normal citizens.
