I've wondered whether people may be blinded by the big sexy conspiracy theories and not looking at simpler more likely options.

The simplest of course is that Oswald did it, but there is at least some evidence for a second shooter from witnesses as well as perhaps acoustics.

The next simplest then is to propose two. What if Oswald had one accomplice who is still unknown because Ruby shot Oswald before he could rat them out.

Why did Ruby shoot Oswald anyway? To stop him from ratting someone else out? Dunno, but these are questions I'd immediately have asked.

What you do in the face of Ockham's razor is gradually dial up the complexity until you encompass all the evidence. You don't leap from simple lone nut to vast conspiracy, but that is what most do.

If there was more than one person involved, the fact that this has remained so mysterious with so many competing theories for so long argues strongly for a very small number of people. The more people are involved the more likely someone would get caught or confess. Death bed confessions are pretty common.
