== The lead == 

 I removed a couple of bits from the lead but was reverted in the name of consensus. So, in the spirit of WP:BRD, I will come here to discuss my edits. I believe that my edits clear up a few basic problems with the lead: 
 *The first sentence is a contradiction—it states that Oswald was the assassin according to three government investigations. However, one of the cited investigations was the HSCA, which found that Oswald was one of at least two assassins. 
 *Oswald was the assassin based on the vast majority modern and reliable scientific evidence. The first sentence (probably accidentally) implies that only the three government investigations conclude that he was Kennedy's assassin. 
 *Why even mention the HSCA in the lead? Its conclusions derived from misinterpreted evidence and have been discredited by modern science. 
 I can foresee reasonable debate on my latter two points, but the first sentence should not contradict itself; it has to be changed.
