Yesterday, 9th Circuit Judge Susan Bolton struck down many of the most controversial provisions in Arizona’s Senate Bill 1070, including the section requiring police to ask anyone they suspect of being undocumented for proof of citizenship. It’s a small victory. Today, a modified version of the bill goes into effect.

Although Bolton’s decision weakened the state law, several problematic provisions remain in place, including one that allows Arizona residents to sue local police for not enforcing SB 1070, as well as one that makes it a crime to knowingly transporting an undocumented immigrant under any circumstance, even in an emergency.
