Political enemies?
They're terrorist suspects, son. And they should be harassed.
Thanks for calling me son, makes me feel younger. Unfortunately many ordinary US citizens whose only crime was writing anti-war pieces have ended up on the secret yellow and red list. Red list, you don't fly at all. Yellow list, you are randomly picked for further searching every time-not very random!
Yes, I have heard from people who found out the hard way that they are on such lists. A red list guy was refused the purchase of his ticket on the computer. No terrorist he, just a political activist. Unless of course you believe that criticizing Bush equals treason, then maybe you find that OK.
