I hope this is because the Feds are investigating Ayers involvement in a 1970s bombing of a SF Police station which resulted in the death of a police officer. The case has never been closed but it seems Ayers and his wife were involved in the Weather underground during the time this bombing occured.

The San Francisco Police Officers Association's leadership has been told to muzzle it after signing a letter accusing onetime Weather Underground radical Bill Ayers and his wife, Bernardine Dohrn, of being behind the nearly 40-year-old bombing at a San Francisco police station that killed a sergeant.
We hear that both U.S. Justice Department reps and Police Chief Heather Fong put in calls to the union to find out just what they were doing talking out of school about an active investigation that may be ready to make a move soon in the 1970 bombing at Park Station.
The word was, button your lips.
Police Officers Association President Gary Delagnes confirmed that his union got a call from federal investigators telling them they had an "active investigation and should not be commenting on the case."
Delagnes said the letter was meant only to show support for the family of the slain officer, Sgt. Brian McDonnell, and to help them "bring closure to the case."
No one has ever been charged in the bombing, and Ayers said last week he had nothing to do with it.
