I love to see it when the passengers take matters into their own hands, do the "profiling" themselves, and refuse to board the planes with those they suspect might be up to no good.
Since the government and the airlines fear the ACLU and so far are too polically correct to profile, the passengers themselves must do it for the sake of their own safety.
The fastest way to force the P C issue is for people to refuse to board (or force the plane to turn back) when they feel uncomfortable.
I would be curious to know who these passengers were. Were they really just random passengers, or were they part of his "contingent", IOW code pinkos, calling in to cause the denial of his "constitutional rights" to wear a t-shirt, in order to set up a discrimination lawsuit?
