Here are some specifics to the case in question.
"In a bombing that took place on February 16, 1970, and that was credited to the Weathermen at the time,[19][20] a pipe bomb filled with heavy metal staples and lead bullet projectiles was set off on the ledge of a window at the Park Station of the San Francisco Police Department. In the blast, Brian V. McDonnell, a police sergeant, was fatally wounded while Robert Fogarty, another police officer, received severe wounds to his face and legs and was partially blinded.[21]
Weatherman leader Bernardine Dohrn has been suspected of involvement in the February 16, 1970, bombing of the Park Police Station in San Francisco. At the time, Dohrn was said to be living with a Weatherman cell in a houseboat in Sausalito, California, unnamed law enforcement sources later told KRON-TV.[22]
An investigation into the case was reopened in 1999,[23] and a San Francisco grand jury looked into the incident, but no indictments followed,[22] and no one was ever arrested for the bombing.[23]
An FBI informant, Larry Grathwohl, who successfully penetrated the organization from the late summer of 1969 until April 1970, later testified to a U.S. Senate subcommittee that Bill Ayers, then a high-ranking member of the organization and a member of its Central Committee (but not then Dohrn's husband), had said Dohrn constructed and planted the bomb. Grathwohl testified that Ayers had told him specifically where the bomb was placed (on a window ledge) and what kind of shrapnel was put in it. Grathwohl said Ayers was emphatic, leading Grathwohl to believe Ayers either was present at some point during the operation or had heard about it from someone who was there.[24]
In a book about his experiences published in 1976, Grathwohl wrote that Ayers, who had recently attended a meeting of the group's Central Committee, said Dohrn had planned the operation, made the bomb and placed it herself.[25] In 2008, author David Freddoso commented that "Ayers and Dohrn escaped prosecution only because of government misconduct in collecting evidence against them", Freddoso wrote.[24][26]

The U.S. government, the courts, and schools of higher learning are either crazy, bought off by enemies of America, or brainwashed to ever give this goon Ayers and his anarchist friends government grants and professorhips. He should not even be given the time of day. Given his crimes, he clearly should have been put in jail for life.
