In June 1969, the Weathermen took over the SDS at its convention. Ayers was made Education Secretary. Later in 1969, Ayers helped to place a bomb at a statue that was made to honor policemen that were killed. The bomb blast broke almost 100 windows and blew parts of the statue onto a nearby street. (The statue was rebuilt and unveiled on May 4, 1970, and blown up again by other Weathermen on October 6, 1970. While they were putting it back together, the city put a 24-hour guard around it to stop another attack. In January 1972, it was moved to Chicago Police headquarters. Ayers was also part of the "Days of Rage" riot that took place in Chicago in 1969. He was also a part of the "War Council" meeting that happened in Flint, Michigan. Two big decisions came from the "War Council". The first was to start a violent, armed resistance (using bombs, and robberies) against the government. The second was to start underground (secret) groups in important cities around the country. An FBI informant named Larry Grathwohl, who pretended to be a Weatherman in 1969, said that "Ayers, along with Bernardine Dohrn, probably had the most authority within the Weatherman".
