The darkly humorous thing is, the new Arizona law closely mirrors the Federal Law in basic wording, in so far as how it treats the people. The big difference is that the Federal Law only allows the Feds to use it - locals are not authorised. So in actuality, it is a turf dispute. The Feds don't get the heat from the latinos because they largely ignore the law, wanting those latinos to support their agenda. Arizona is upsetting their applecart.
