Well, The Nr Fairy, Section 5.4 goes a little into that. Are we getting to the stage that "Reasonable suspicion cannot be based on generalisations or stereotypical images of certain groups...."? Are pilots suffering from stereotype? I suggest there's growing evidence to support that we are.
The other interesting part of the FODCOM (UK, not US) is Section 6.3:
"Flight crew and cabin crew who are required to take a preliminary test, witha negative result, may decide that it is unsafe for them to operate because of the emotional impact."
Maybe you should just go sick, have the police make the announcement to the passangers that the test was negative, however the flight has been cancelled due to lack of crew?
Cheers,
