If the public can be convinced it was a single gunman, then it is single crazy nut, end of a sad story.
And the best way to convince them of that is to have multiple shooters spread all over the place, is it?
If there were more then one shooter, it is a conspiracy.
Which, as I and others have said, is a damn good reason
not to use multiple shooters if the planned cover story is that one lone nutter did the job, or to have the lone gunman as a cover story if you are going to use multiple shooters.
Ludicrous plan? What are you talking about, it worked didn't it?
Nice circular reasoning there.
Are you seriously suggesting that a conspiracy was hatched to convince the world that Kennedy was shot in the back by a lone gunman and that to do this they decided to have a few gunmen dotted around the location? Forensic analysis of bullet trajectories was quite a mature science by that time. Why hatch a plan that runs the risk of discovery if they find that he was hit by two bullets going in opposite directions?
You have yet to prove that there were multiple shooters. If you can manage that I'll be impressed. So far you don't seem to know what evidence is, and your own links to evidence include things that contradict the statements you are trying to support.
