Excerpt:
“Three gunshots, of course, is in keeping with a lone assassin theory - or is it? If there exists the possibility that silencers could have been utilized by one or two additional gunmen, then the earwitness testimony may very well become irrelevant no matter how many shots were “heard.” Acting on the assumption that a multi-gunmen crossfire, if one existed, would have to be carefully planned and executed, this researcher considered the means by which ballistic evidence could be manipulated. I tried to imagine how a triangulated gunfire could succeed while implicating one lone shooter in the Texas School Book Depository. My research led to the consideration of silencers and the characteristics of typical sniper weapons available in the year 1963. The results of this research should give pause for thought and cause us to re-examine the ballistics evidence and the medical evidence from a different perspective.”
