Summary: Doubt continues to surround the assassination of President Kennedy to this day. Unfortunately, the controversy was not diminished by the multiple commissions and panels that were convened to investigate it. This was in large part because these various panels continued to propagate much of the confusion and lack of precision that plagued the initial medical reports, and introduced some new confusion of their own. Much of this controversy was driven by incomplete information, poor documentation and analysis, and the puzzling decision to withhold key medical evidence both from investigators and the public. However, the preponderance of evidence does show that the single-shooter, three-bullet theory is plausible both medically and scientifically.
