Proof of Citizenship Card, Please

Immigration debate - seems to be a very hot topic these days with the Governor of Arizona giving the police the right to question citizenship.

I have an idea. When going to the Department of Motor Vehicles for a US Driver's License, I think you should be required to show proof of citizenship (SSN?), or proof that you are in this country legally.

Show the proof, get the license and have the DMV also issue (at the same time) a proof of citizenship card complete with a picture. Then we need to make it standard operating procedure for all police departments throughout the US that when pulling over a driver they need to ask for (1) driver's license, (2) registration and (3) proof of citizenship.

This would become SOP for all Americans; therefore, eliminating the response that the police are profiling.

I think if immigrants are in the US legally, there should be nothing to worry about, and if they are not, they should be worried. They should be deported, and then allowed to apply to enter this country legally as millions have done throughout our history. I want the USA to be a country that welcomes immigrants from throughout the world, it is what this country is all about....I just want everyone to play by the rules, and do it legally!
