However, we must be able to easily identify anyone who does not have a right to be in this country.
Your rant doesn't explain how we might do that without a national ID card.
Cards would not work for obvious reasons. A laser mark would be there to stay, but there's no guarantee it woulud be used for ID of aliens--very possible they would use it to know everything about citizens, not illegals.
Have you wondered how the law would be enforced? Can you say "Police State"?
