In real security, if you aren't proflining then you are doing something wrong.
It may not be "democratic" and it definitely isn't "fair". But in matters of life and death democratic and fair have no place.
The argument that those who want to defeat security will defeat it eventually has no merit. Yes there are aryan looking terrorists and huge numbers of peaceful men of middle eastern descent. However, as long as you are profiling correctly, then it isn't racism, it is security.
And if it ISN'T security, then what is it? It is a sham, a nostrum, an exercise in societal masturbation fantasizing about security.
Profiling has a place, and as long as you can update your profiling criteria as the threat changes, it is a useful tool.
