Mass. Sheriff: Arrest Sanctuary City Leaders:  Bristol County Sheriff Thomas Hodgson told a House Subcommittee Monday that the leaders of sanctuary cities should be arrested for obstructing federal law.  CBS Boston reports that the Sheriff told committee members that sanctuary cities "have become magnets for illegal aliens, some of which have violent criminal records."  He also called out a Massachusetts legislator Michelle DuBois who passed along rumors of a planned ICE raid in Brockton, posting on Facebook "if you are undocumented don't go out on the street. If there is a knock on the door...and you don't know who it is, don't open the door."   "Any person who actively incites panic or fear of law enforcement is doing a disservice to the  community, endangering public safety and the very people they claim to support and represent," said Shawn Neudauer of ICE. Democrats across the commonwealth have pushed back and said they stand with sanctuary cities.
