How many of these demonstrators really want citizenship and how many just want to stay here without being a citizen? And how are they ever going to check who's who anyway when some of them have fake documents (SS cards, Green cards, etc.?)
Why would they want citizenship? If they got it, then they'd have to pay income tax, pay for their food, medical care, education, etc., etc. like the rest of us schmucks. That's the last thing they want. Right now they've got a carefree life subsidized by the American suckers.
