It bothers me that this discussion is seeking to create a caste system between flight crew (pilots) and the greater masses of the unwashed.
There are some good arguments about bonafide card carrying pilots being low risk, But I must remind you that there are equally good arguments about a much larger percentage of the general population being equally low risk. The more that the small population of pilots push for their own sphere of declaring themselves low risk, the more that the much larger population of the general public are going to rebel against one group being declared more clean than themselves. I would much more be inclined to support a petition to either lower the overall security visible inconvenience for all or at least demonstrate that the relief is not exclusive of a larger majority of low risk individuals.
