Every year the British Medical Journal publishes a christmas edition containing humorous, not entirely serious, and/or particularly topical articles.
This year it includes a suggestion for an experimental investigation of airport screening effectiveness.
Screening programme evaluation applied to airport security (http://www.bmj.com/cgi/content/short/335/7633/1290)
Essentially the suggestion is to use the techniques that would normally be used to establish the efficacy and cost-effectiveness (i.e. a clinical trial) to investigate airport screening.
Whether the particular study they have suggested would be practical or sensible this article does draw attention to some important issues.
In particular, the authors have looked at the scientific literature and found...
"...no comprehensive studies that evaluated the effectiveness of x ray screening of passengers or hand luggage, screening with metal detectors, or screening to detect explosives."
