What are the implementing instructions for such a grandiose scheme? Ask nicely? Cattleprods?
We did it for MANY MANY years. It used to be that the INS had green buses that would show up at employers and ask for their green cards.

It ain't that tough. Your mind is just too simple to wrap itself around doing the right thing.
There are hundred of thousands of crimes happening. DAILY! That is too many to actually COMBAT.
Your way of doing nothing is clearly the proper way to proceed.
