Philadelphia police surrounded a row house where members of a radical back-to-nature group live and ordered residents to evacuate the neighborhood. Residents have pressured city officials to enforce sanitation, health and building codes at the house, where members of the group called MOVE have set up a rooftop lookout tower and have boarded up windows. Police reportedly were negotiating with the group to get them to leave the house or face forcible eviction. The last such confrontation between MOVE and authorities ended in the death of one policeman in a shoot-out in 1978. Nine MOVE members are serving prison terms in connection with the slaying.
