I agree with you 100% on security theater, but you have to be careful with "intelligent profiling." Remember that if it involves singling somebody out by race, gender, religion, etc., it's almost certainly unconstitutional in the US.
by intelligent profiling, I mean more the way the Israelis do it: psychological profiling, looking for telltale signs of nervousness/guilt etc., ranking people by profession/origin/appearance, and randomly singling people out for more extensive scrutiny (but not so random as to nab the 80-year-old grandmother in a wheelchair).
Instead, we prefer to use metrics, which we can mesure, aggregate and compile in neat reports. But metrics are a projection of a multidimensional situation onto a few dimensions, and hoping we picked the correct projection.
I'm all for collecting stats but I wish that was just a tool used in addition to a broader qualitative approach.
