Is Eric Holder is too busy investigating Sheriff Joe to bother with Obama's unrepentant terrorist buddies?  "The San Francisco Police Officers' Association (SFPOA) tells Cliff Kincaid of America's Survival, Inc. that evidence in the 1970 bombing murder of a San Francisco police officer points to Weather Underground members Bernardine Dohrn and Bill Ayers, two associates of President Barack Obama."

"There are irrefutable and compelling reasons to believe that Bill Ayers and his wife Bernardine Dohrn, members of the terrorist group 'Weather Underground', are largely responsible for the bombing of Park Police Station and other police stations throughout the United States during their 'tour of terror' in the late 1960s and early 1970s," the SFPOA letter states. The SFPOA letter is signed by all five officers of the SFPOA

The letter, dated Feb. 24, is signed by union President Gary Delagnes, Vice President Kevin Martin, Secretary Tony Montoya, Treasurer Martin Halloran and Sergeant at Arms Christopher Breen. ...

"It's coming directly from a person who had close, confidential conversations with Ayers and members of the Weather Underground," Martin said. "We have no reason to doubt his assertions."

Martin said the union wanted to "bring this case to attention, especially because Bill Ayers has been on a speaking tour. His actions have elicited this type of response."

The attack happened Feb. 16, 1970, when a bomb placed on a window ledge of Park Station at Waller Street and Kezar Drive killed McDonnell and injured eight other officers. The case got attention two years ago when prosecutors charged a group of alleged former Black Liberation Army members in the 1971 shooting at the Ingleside Station that killed Sgt. John Young.
