A new group, composed primarily of Boerum Hill residents, has been organized to resist the plan to reopen and expand the Brooklyn House of Detention on Atlantic Avenue. This past weekend, a small army of volunteers started a door-to-door canvass of both residents and storeowners to convince them to oppose the expansion plan. Posters with the request to âStop the Jailâ were passed out and have begun to appear in the windows of homes and stores in the area.
