Maybe with the development and breakthrus with DNA and Other Forensic Sciences, William Ayers can be indicted, and stand Trial for Murder in the First and/or Second Degrees.
His famous quote “Guilty as Hell, Free as a Bird” will not play well in front of a Jury today. Killing anyone is Unforgivable, Killing Policemen must be prosecuted till the ends of Earth! and those Murders were a Federal Crime!
