From Stateline:

The governors of New York and Massachusetts recently joined Illinois in ending participation in Secure Communities on the grounds that very few of the people being deported have been convicted of serious criminal offenses. The issue is now heating up in California and Colorado, too.

The uproar over Secure Communities is part of the larger debate about how far states should go in cracking down on immigrants who are in the country illegally. Like the controversial immigration law passed by Arizona last year, it raises the question of how deeply local police departments should be involved in enforcing federal immigration laws.

The federal government later announced that Secure Communities was not voluntary, but the legal wrangling continues.
