of the TSA's approach to airport security. Once all Arizonans are required to present their papers daily to every law enforcement officer that crosses their path, will people wonder whether this cost is worth the "benefit" of a society that is free of undocumented foreigners? Will Arizonans who feel that they are "obviously" not illegal aliens begin, I don't know, sporting American flag lapel pins at all times, or wearing a sign around their neck saying "I AM AN AMERICAN"? It won't work, of course, because such accessories will quickly become popular with bona fide illegal immigrants as well. Maybe Arizona could pass a new law requiring American flag lapel-pin suppliers to verify the immigration status of anyone who buys one, or maybe we'll have to carry a special permit that entitles us to wear lapel pins or signs around our neck. It sounds pretty awful, but that's the price of liberty."

Reactions of "Arizonans who feel that they are 'obviously' not illegal aliens" would cause such a political blow-back that politicians will backtrack so fast it will make heads spin.
I kind of like the idea of an "I AM AN AMERICAN" pin with the requirement that suppliers have to check citizenship or immigration status of anyone who buys the pin. ;)
