So, what have YOU done lately to help "enforce" immigration code? When was the last time you've filed a complaint against an illegal alien with your local ICE office? if ever?
First of all, Charlie is right on as usual. Second, what you propose isn't that simple. As an employer, you can refuse to hire those without proper paperwork. As a citizen, good luck reporting the crowd waiting for work at the local park. Nevermind, Home Depot is their gathering spot now, and ICE doesn't seem to care.
Now I can have suspicions about the man selling bedspreads, or the lady selling tamales(buy them, they're delicious!) in the grocery store parking lot, but I'm basing my suspicions on their skin color and language/accent. I'm not going there, if you know what I mean. You see? It's not that easy. Oh, I understand why you posted what you did to who you did, but in reality, it just isn't that simple.
Charlie Daniels kicks ass : )
