You aren't trying to say that the feds are enforcing the illegal immigration policies, are you?
They've been notified of clear cases of illegals at various companies and largely ignore the complaints is just one example I can think of.
If you were to call up the IRS tomorrow and tell them that your next-door neighbor filed a fraudulent tax return last year, I'm pretty sure the IRS isn't going to spring into action and show up on his doorstop just because you told them so.
