CNN has some better information available. Apparently DHS is not ordering him not to enforce laws. There was an agreement between DHS and Arpaio that Arpaio would enforce federal immigration law as a delagation of DHS's authority. DHS is now terminating that agreement.

That distinction has direct impact on a lot of the posts in this thread - mine included. Given the situation, I have no problem with DHS or Nopolitano's actionsSheriff Joe Arpaio and the Maricopa County, Arizona, sheriff's department have had an agreement with the Department of Homeland Security since 2007 that allows his department to enforce federal immigration laws. But Arpaio says the federal agency is moving to revise the agreement to limit that power to checking the immigration status of inmates already in his Phoenix jail.
If his stops were handled like a DUI checkpoint where every car or every third car was stopped and drivers license, registration and insurance were checked, he would have probable cause to check the immigration status of all who could not provide those documents that are required by state and federal laws.
Anyone have a problem with this style of check since it is not based on race but on required documents that we all must carry with us when we drive?
Interesting similar material.

The report also raised questions regarding a proposal by ICE to revamp its agreement under which sheriff's department personnel check the immigration status of inmates. The report said the proposed changes would shift more of the burden of processing deportation papers to sheriff's personnel, putting a strain on jail staff.
