not at all, many people around the assasination were murdered...that is a researchable fact. They simply were in fear and changed their original observations. The honest thing to do is look at what they originally observed, not what they said later under duress. Those are the facts, what they observed originally. Sorry, but any amount of twisting just doesn’t cut it except for very gullible people. Posner is not very astute and his book doesn’t hold a candle to the many very reputable researchers and scientific experts who have written about the obvious mutiple field of fire that took place.
No they weren't.
