Bill Ayers helped form Obama's positions. I know undercover operations are important to protect all of us - but the FBI can't be the political enforcement arm of the democrat party...
“Deep Throat” is the guy who botched the Bill Ayers case.
...Refusing to testify, all were incarcerated for the 18 month life of the special tribunal and later freed on appeal due to suspected wiretappings and mail openings. Four months afterwards the cases were dismissed[92][93][94] The decisions in these cases led directly to the subsequent resignation of FBI Director, L. Patrick Gray, and the federal indictments of W. Mark Felt or “Deep Throat” and Edwin Miller and which, earlier, was the factor leading to the dismissal of federal “most-wanted” charges against members of the Weather Underground leadership in 1973.
