In 1970 she was put in prison by FBI agents. Some black revolutionaries tried to break their allies out of prison by kidnapping a white judge and some jurors in Marin County, but the police didn't let them get away and the revolutionaries and judge were shot to death. The FBI suspected that she bought the gun one of the revolutionaries used and decided to accuse her of the murder of the judge. In 1971 she appeared at the Marin County Superior Court and said, "I now declare publicly before the court, before the people of this country that I am innocent of all charges which have been leveled against me by the state of California." She was released from jail in 1972. Ronald Reagan said that she should never be allowed to teach at a California university. The English rock band The Rolling Stones recorded a song called "Sweet Black Angel" that was on their 1972 album "Exile on Main St." and dedicated to Davis.
