In a protest against the removal of protections under the Deferred Action for Childhood Arrivals (DACA), over two dozen professors and affiliates of Harvard - as well as Babson College, Massachusetts Institute of Technology, UMass Boston, and Boston College - were arrested in Harvard Square yesterday after creating a human chain across Massachusetts Avenue that blocked traffic through the busy Cambridge junction.

With the Deferred Action for Childhood Arrivals program formally rescinded (with a six-month implementation delay), there have been a lot of questions about whether the databases created for the program - as well as state and local support programs - could ultimately be used against DACA recipients. Last November, one DACA recipient predicted just that situation in an unsuccessful plea to former President Barack Obama to delete the database, and now the issue is likely to play out across states and municipalities throughout the United States.
