The Arizona law makes it a state crime to be in the U.S. illegally

Should be obvious. ...like saying "the new law makes it a crime to break the law."

Yeah it should be obvious .... but merely the fact that they had to pass a law to enforce the already-existing laws shows just how out-of-control this whole political-correctness thing has become.

Maybe this marks a turning-point, which is why the activists are so choked?

The Arizona law makes it a state crime to be in the U.S. illegally.
The Arizona law adds the penality of making it a state crime in addition to the federal crime of being in the U.S. illegally.
