After a second fatal shooting of an American citizen during ICE’s immigration crackdown in Minneapolis this month, Gov. Maura Healey announced Thursday that she filed legislation to block ICE agents from entering courthouses, schools, child care programs, hospitals and churches. “It used to be that federal agents and partners in law enforcement recognized those sensitive spaces, and they, in fact, used to designate them as sensitive locations that were protected from enforcement action," said the governor. Healey’s bill would also make it unlawful for another state to deploy its National Guard in Massachusetts without the governor’s permission. It would also allow commonwealth parents to pre-arrange guardianship for their children in case they are detained or deported.
