No, I am an American.
But I LOOK like a JEW.
Ya get my point?
Slippery slope. If the police can stop you on the street, or in a car and 'ask for your papers'; essentially single you out for an inspection - then can they stop you, and if they see something wrong, can arrest you. You are now no longer protected from search and arrest, as the whole 'Reasonable Cause' clause has been bypassed.
Next, will they be able to search your home for illegals - oh, and by the way we found that you have an unregistered firearm... Slippery slope, folks.
Now, as a aside - I want every illegal shipped out. Don't care if they have babies, kids in school, started a business - that's their problem, not mine. They created the mess, I don't see why they should get special consideration for breaking a law, then cluttering up their actions with even more screw ups. But, the idea of randomly asking people to produce proof of citizenship should be tied to a formal Gov't sanction .... like if we are at war.
We are at war, so for now, I'd let this slide. When we 'win' the war, this law would be limited in scope. Routine traffic stops, ect. But, the law is NOT tied to any gating function - so I have some concerns that a politican will pervert this law (I know, imagine a politican perverting a law for personal gain).
