There was a pretty lengthy discussion about it here, but I'm not sure how to search the forums anymore.
Anyway, that's not entirely accurate. If someone is stopped for another offense, the police officer can ask them about their immigration status if there's reasonable suspicion that they're in the country illegally. It's really not a huge departure from current law, and the only reason there's a firestorm around it is because Arizona intends to actually enforce it.
