She referred to a May 1985 standoff between the organization MOVE, a back-to-nature and Black-liberation group that was housed about a third of a mile from 61st and Locust Streets, where police shot Wallace Monday night. MOVE participants at the organization’s communal home in Cobbs Creek had protested the arrest of nine of its members in connection with the shooting death of a police officer seven years earlier. A daylong confrontation with police ended when the commissioner, Gregore J. Sambor, authorized a helicopter to drop a bomb on the compound. The bomb started a fire that the commissioner ordered not be put out, and 11 people, including five children, died. The fire devastated the residential community, damaging 60 homes.
