I think a National ID card could save my life! I'm envisioning something like a "sandwich board" that could hang over my shoulders and cover me front and back from neck to feet. It would be bullet proof, fire proof, bomb proof and knife proof. Maybe it could even have ventilated side panels.
Unfortunately anything short of that probably wouldn't make us safe, it would just give us more daily hassle carrying and displaying one more form of ID. As to criminals being stopped in other states, I haven't heard if the hijackers were ever stopped for traffic offenses or checked for ID. These guys lived real quiet lives, were good neighbors and for all intents and purposes up until the last day, reasonably good visitors. So, unless EVERYONE were checked for their National ID ALL the time, there would be no way to know if these guys were legal or not without Racial Profiling. Green Cards? These guys didn't even have valid Visas.
The Friday after the plane bombs hit, our local police picked up a gentleman who claimed to be Mexican. Through an interpreter, he explained that he grew up in the US. He couldn't speak a word of english. Being suspicious types, the local sheriff called INS and asked them to have a hold put on the guy so they could keep him long enough to check things out. INS said "Sorry, can't do it. It's after closing time. It'll have to wait until Monday."
I understand in Afghanistan, there is a large Hindu population. The Taliban has ordered all of them to wear a badge so they will be easy to identify. Sort of what the Nazis did to the Jews. I liken a National ID card to that, only in reverse. It says you're a member of the preferred club.
