This entire debate would be over if closing the border meant BOTH sides and requiring ID meant from EVERYONE not just Hispanics.
In fact, Arizona should first put their law enforcement thru a background check to make sure they are legal. They should sign a binding affidavit that they have no illegals as relatives nor are friends and family married to or dating illegals. THEN they can go about carding EVERYONE, even the guy living in their town some 70 yrs and fought in WW2; I mean how do we know his parents didn't illegally bring him from Hungry or Germany?
This really is a loser issue: if you don't treat everyone the same, you open up endless racist charges and suits. If you do, you go bankrupt with the manpower needed
