People in question here are green card holders, as such they have same rights as pernament citizens, other then voting or holding the top secret clearance.
They are screened heavly, and only the lukiest ever get the green card, which still remains a dream for millions of those who are here illigaly.
To require citizenship from a airport screener is silly, seeing as we do not require citizenships from those who fight for USA. I've entered US Navy with greencard, and didn't become a citizen till after i left the service.

Hand that feeds me ? I've earned my citizenship, how about you ?
So now that i am a citizen i have to be an ignorant bastard and dismiss all others not worthy ? I never quite considered my passport to be a validation of my superiority..... but if you say so..
