Ok, since I really enjoyed the video below, I thought to read the short (16 page) Arizona immigration bill (PDF) myself and see what all the hubub is about. Even though I am politically conservative, I do believe we need a compromise solution that enforces our borders and has compassion on people fleeing the poverty and corruption of Mexico (though the current administration is trying hard to shut down the drug cartels).
Summary? I think the law is a little too harsh, but only a little. Even 'worse,' AZ Senator Russel Pierce argued on The O'Reilly Factor last night (also below) that giving citizenship to the children of illegals born in the US is NOT covered by the Fourteenth Amendment, nor by court cases since. His argument is very interesting, and not out of the question.
