Calloway was not flying the plane!
From the Wikipedia article you linked to (twice) but apparently did not care to read:
"The scheduled three-man flight crew consisted of 49-year-old Captain David Sanders, 42-year-old First Officer James Tucker, and 39-year-old Flight Engineer Andrew Peterson."
"About twenty minutes after takeoff, as the flight crew carried on a casual conversation, Calloway entered the flight deck and commenced his attack."
This incident is therefore entirely irrelevant to the conversation.

It's interesting, though, to find (articulate) American people who actually approve of the TSA methods, because I thought it was the TSA vs. the rest of the public (cf. "Ask the Pilot" Salon column for instance).
It's interesting, but disheartening, because it means the TSA and its gropers and thugs are really here to stay.
