"Do I have the right to refuse this search?"
This is a question I heard many times during my law enforcement career. Often my answer was no. But occasionally it would be "yes," followed by an admonition to have a good day.
....
Within the last few months, I have been singled out for "additional screening" roughly half the time I step into an airport security line. On Friday, October 9, as I stepped out of the full-body scanning device at BWI, I decided I needed more information to identify why it is that I have become such an appealing candidate for secondary screening.
....
Finally, I am most concerned about the "random" nature of my repeated selection for secondary screening. If there is no discrimination at work, and my selection is entirely random, then we have yet another, and probably more significant problem.
For years in policing, we relied on random patrols to curb crime. We relied upon this "strategy" until someone went out and captured some data, and did a study that demonstrated conclusively that random patrols do not work (Kansas City Study).
