An audio forensic analysis by Catalin Grigoras, director of the National Center for Media Forensics at the University of Colorado in Denver, and Cole Whitecotton, a senior professional research associate at Media Forensics, based on audio recorded in Butler, Pennsylvania, may show the possibility of a second shooter.

According to these experts, "The first three shots were consistent with alleged weapon A, the next five were consistent with alleged weapon B and the final 'acoustic impulse' was emitted by a possible weapon C." We know that one of those was the identified shooter and another was a Secret Service sniper. We don't know to whom the "possible weapon C" might have belonged. A second shooter? The armed spotter on the government sniper team?

Only one shooter has been identified and the FBI says he acted alone. The bureau may want to reconsider its conclusion.

Obviously this controversial audio forensic analysis needs peer review. But there are other questions beyond the audio forensics that need attention.

Below I review some of what we know, and a lot we don't know, and I ask questions where the information we have so far leads.

I, among thousands of others, became a sort of student of the John F. Kennedy assassination. I have read tens of thousands of pages from books and articles.  But what turned out to be most impressive, as far as I am concerned, are two things.

Firstly, in my opinion there was a massive coverup that still continues sixty one years after Kennedy was killed.

Secondly, apparently President Trump withheld releasing some documents even though he had pledged to release everything still in the archives on the Kennedy killing. He allegedly told Roger Stone that he (Stone) "would not believe what is in the [still] classified [and unreleased] files."
