As Congress considers revisions to federal immigration laws, legislators in a few states are trying to block the federal government's power to deport immigrants who land in their jails, reports Stateline. The efforts to pass so-called Trust Acts are the polar opposite of laws passed in Arizona and elsewhere to encourage illegal immigrants to leave their states. Sponsors want to put the brakes on the wide-reaching Secure Communities program that asks state and local police to detain illegal immigrants after an arrest until federal immigration officials can pick them up. Critics of Secure Communities argue that the program leads to the deportation of some people who pose little threat to the public. The public push to pass Trust Acts started in several state capitols this month, including California, Connecticut, and Massachusetts.
