Breaking news from the AP:
A judge has blocked the most controversial sections of Arizona's new immigration law from taking effect Thursday, handing a major legal victory to opponents of the crackdown.
The law will still take effect Thursday, but without many of the provisions that angered opponents -- including sections that required officers to check a person's immigration status while enforcing other laws. The judge also put on hold a part of the law that required immigrants to carry their papers at all times, and made it illegal for undocumented workers to solicit employment in public places.
*** UPDATE *** Per NBC's Pete Williams, here's a statement from the Justice Department:
"We believe the court ruled correctly when it prevented key provisions of SB1070 from taking effect. While we understand the frustration of Arizonans with the broken immigration system, a patchwork of state and local policies would seriously disrupt federal immigration enforcement and would ultimately be counterproductive. States can and do play a role in cooperating with the federal government in its enforcement of the immigration laws, but they must do so within our constitutional framework.
"This administration takes its responsibility to secure our borders seriously and has dedicated unprecedented resources to that effort. We will continue to work toward smarter and more effective enforcement of our laws while pressing for a comprehensive approach that provides true security and strengthens accountability and responsibility in our immigration system at the national level.
