DARTMOUTH — Bristol County Sheriff Thomas Hodgson attacked as “baseless” and “politically motivated” this week’s report from Massachusetts Attorney General Maura Healey that accused his officers of using excessive force and violating detainees’ civil rights during a May 1 melee at an immigration detention center in Dartmouth. “The attorney general’s report goes to incredible lengths to dismiss and discount the truth about what really happened,” Hodgson said during a press conference Wednesday at the Bristol County House of Correction. Hodgson said Healey’s investigators never interviewed him and left out evidence that he was struck by a chair that a detainee is alleged to have thrown at him during the fracas, which was sparked by detainees refusing to be taken to the jail’s medical wing to be tested for COVID-19.
