On a cold Friday afternoon, Thomas Brouillette leaned against the brick wall of the pumping station next to Damon’s Beverage and Redemption on Washington Street as a red shopping cart full of his belongings shielded him from the first snow of the year. About 1 p.m., Bangor police Sgt. Wade Betters and the city’s outreach worker, Torelin Jager, pulled up in an unmarked police cruiser to talk to Brouillette and the two men with him. Brouillette, 63, has been living on the streets of Bangor for months, but he recently got a hotel room for a week when his Social Security money came in.
