All the indicators are just total nonsense. Off the top of my head I remember excessive whistling, sweating, and leg shaking. And to show exactly what these people are actually worried about, one indicator is contempt for the screening process. Right. Right. A terrorist isn't going to go through smoothly and quietly, he's going to observe all the foolish things the clerks do and their violations of the rules and make a ruckus and call attention to himself. I think all the indicators are just random except for the ones designed to characterize disrespecting the clerk's authoritah as nefarious. The whole list was done in bad faith.
