What does it say about conservatives when they support the Arizona immigration law?

I think we all agree there is a problem with illegal immigrants in our country. My issue with this law is that it doesn't stop illegal immigration. I'm reading a lot of responses saying you have to be doing a crime but the law doesn't say that. "Lawful contact" is not explained. Their shouldn't be any room for umption...bottom line. No matter how many you send back it still doesn't stop your problem. All this law does is divide. People, drugs, weapons, and whatever else will still come across the border. Fix that! "Reasonable" yeah right. And yes I've read the bill. There is nothing in there that says you have to be commiting a crime before this law is enforced. If so, show me, and not your umptions...but facts.
