As a regular business traveler, I can see no better way to form two lines at the airport (citizens and non-citizens) thus giving the latter more scutiny.
It works in Europe, South America and other places around the world that have had to deal with terrorism on thier shores for a good number of years.
Are we to wait for the government to somehow make our pourous borders work?
Or to issue everyone passports instead - very illogical (besides, one of the terrorist got in on a phony passport from a non-existant country)
Or should we just continue to rely on our state issued drivers license that is easily forged (heck, there are 50 systems for them to pick from) - where states like Tennessee and others are already issuing to illegal immigrants ...
No, let's continue to make emotional "I don't want it" arguments with no basis on the real goal of getting this country moving again.
