AZ is trying.. we managed to get PART of AZ SB 1070 through, the rest we will take all the way to the top. We have been using E Verify for years now. It works, but is limited, because illegals have access to "clean" SS numbers that can sneak through E Verify. We TRIED to pass a bill that would ask for proof of citizenship to register in school, and in the ER... it failed, which is quite odd, because I had to show my kids BCs, shot records, lots of things, to enroll them in school.. We managed to pass a bill that makes it illegal to RENT to illegals, which includes motels, apartments, homes, etc, but of course they get around that by having legal citizens do the paperwork. The transportation of illegals is illegal in AZ, and people go nuts... like it will affect THEM if they give the neighbor lady a ride to the grocery store. In reality it affects human smugglers, but people just love to find that tiny possibility that it could cause trouble to law abiding citizens.
By the way-- the ER thing would NOT have denied treatment. The patient would be treated for whatever they come in for, then turned over to border patrol. But, of course, the protest was that AZ would let people die in the streets, spread horrible diseases, etc. It's time to face the reality that the Feds do not want to stop illegal immigration. Guess I should add JMO to that.
