S.F. police union accuses Ayers in 1970 bombing

The San Francisco Chronicle reports:

Leaders of San Francisco's police officers union have accused Weather Underground co-founder Bill Ayers and his wife, Bernardine Dohrn, of taking part in the 1970 bombing of a city police station that killed a sergeant.

The union leveled the charge in a letter to a conservative organization lobbying for arrests in the case, but said it had not been in contact with investigators and had no new evidence related to the bombing, which killed Sgt. Brian McDonnell.
