Every tactical move was telegraphed to the house via bullhorns. One of their first tactics was to turn fire hoses on the house. The police even considered the depth of the basement of the MOVE house and the height of the basement windows, to ensure that nobody would drown if the basement was completely flooded.
Who began shooting is disputed; MOVE claims that they never fired a shot; videotape shows muzzle flashes from the basement windows of the MOVE house. One police offiver, James Ramp, was killed. Rizzo had the house demolished the next day. Leaphart and eight other MOVE members were sentenced to prison for the murder.
MOVE moved to a house in west Phildelphia owned by Louise James, a relative of a MOVE member. They continued their back to nature philosophy, and added a new agenda, freeing John Africa (Vincent Leaphart). In a change from their previous tactic of staging protests downtown, MOVE began to pressure their neighbors. The Osage Avenue houses were connected, and their roofs formed a convenient jogging track for MOVE. Neighbors listened to the MOVE physical training program through their bedroom ceilings. Neighbors complained about that, and the public address system that MOVE used for political diatribes, as well as the smell of human and animal waste. Then Managing Director W. Wilson Goode was ran for mayor, and the neighbors were convinced that Philadelphia's first African American mayor would be able to reason with MOVE, so they did not press the issue pending the election. Goode was elected in November of 1983. The situation on Osage Avenue did not change.
On May 13, 1985, in a failed attempt to serve arrest warrants on four members of the group, Philadelphia police became engaged in a gun battle at MOVE's communal residence. They eventually decided to drop a bomb on MOVE's rooftop structure alternately described as a "gun turret" and as a purely defensive fortification. The structure was unoccupied at the time. This bomb started a fire which destroyed the entire block and killed eleven people. Ironically, the city's best firefighting equipment had been trained on the rooftop bunker all morning, but "the decision was made to let the fire burn" in the words of police chief Gregore Sambor. 62 houses burned to the ground; only Ramona and Birdie Africa escaped. Six adults and five children in the MOVE house died.
Police initially said they had been fired upon first with automatic weapons, but only a small number of non-automatic weapons were found in the burned-out home. MOVE supporters have described the raid as a revenge attack for the 1978 shooting.
In the aftermath of the catastrophe the city launched a special investigation which found, among other things, that "Dropping a bomb on an occupied row house was unconscionable." Philadelphia has paid $26.5 million to the victims after various lawsuits.
