Quite literally while I was in mid-air en route to Arizona, U.S. District Court Judge Susan Bolton in Phoenix issued a ruling on SB 1070. Some aspects of the law can go into effect, but she has issued a preliminary injunction against its more controversial sections, which empowered local officers to check individuals' immigration status while conducting other law enforcement, and required immigrants to carry documents. Republican Gov. Jan Brewer said the state will likely appeal the ruling. More to come.
