Federal Judge Susan Bolton issued a blow to Arizona's controversial immigration law Wednesday, blocking key parts of the law, including the provision that requires immigrants to carry their papers with them at all times. We take a look at how long the injunction will stay in place and what Arizona's next legal move might be. And we ask what this means for other states that want to craft their own immigration policies. 

We've all heard a lot about Arizona's controversial and stringent immigration law, SB 1070, which allows Arizona police to question anyone they suspect may be in the country illegally. But 44 other states have introduced immigration legislation of their own since the beginning of 2010. Some worry that the U.S. may soon be facing a patchwork of different laws for different states.
