Brendan, your contentions are naive and poorly timed.
As of last week, Ayers is now an accused cop-killer and there is no statute of limitations on murder.
Ayers is a member of a group that killed at least three police officers. The Weather Underground also supported other radical groups that murdered nine other police officers in cold blood.
The relationship between Ayers and Obama was not a casual one. From 1995 to 2001, they served together as directors of the Chicago Annenberg Challenge. This leftist board (funded by a wealthy Republican, interestingly enough) doled out more than $100 million, much of it to radical groups. In fact, during his failed run for Congress in 2000, Obama claimed this experience with Ayers as his central qualification.
Ayers and Obama also served on the board of the Woods Fund, which funneled money to controversial groups like ACORN -- infamous for rampant voter registration fraud.
Ayers, to this day, is unapologetic about his terrorism and his revolutionary goals. He vocally supports the overthrow of the U.S. government on his blog. And in his memoir, Ayers declines to specify the bombings he participated in, writing that "some details cannot be told."
Speaking at the National Press Club last week, representatives of the San Francisco Police Officers Association stated that they believe Bill Ayers and his wife Bernadine Dohrn arranged the 1970 nail-bombing that killed San Francisco police officer Sgt. Brian McDonnell.
Larry Grathwohl, an FBI informant who infiltrated the Weather Underground, stated, "I have testified, spoken, and written about the involvement of Weather Underground terrorist leaders Bill Ayers and Bernardine Dohrn in [the] bombing on February 16, 1970, [that] took the life of Sergeant Brian V. McDonnell. There is no statute of limitations on murder."
