MOVE

In 1977, the police under Mayor Frank Rizzo obtained a court order requiring MOVE to vacate their Powelton Village house at 311 N 33rd Street. The group had begun to occupy the residence, and it was not long before MOVE's living style exhausted their neighbors' patience. MOVE members made a treaty with the police. They agreed to move out of the premises and surrender their weapons if the police released their members who were held in city jails. The police held up their end of the deal, but MOVE members failed to comply.^[15]
