What are the unresolved variables?
For one, they looked at a "three shots fired, three shots hit" scenario. That didn't fit. The better question would be "What other possible scenarios have been looked at that did fit?" I've seen numerous attempts made but most of them are farcical.
What are the unresolved variables?The exact positions of Kennedy and Connally relative to each other at the moment of the shot(s), the exact posture of Kennedy at the moment of the shot(s), the exact location of the car at the moment of the shot(s). There has been 56 years of discussions about this and there is still no mutual agreement.
For one, they looked at a "three shots fired, three shots hit" scenario. The "three shots fired" scenario is just about the only thing they ever looked at. The "three shots hit" scenario was the initial assumption until they found they only had two bullets left to account for all the wounds which of course was why the SBT was concocted.
The better question would be "What other possible scenarios have been looked at that did fit?" I've seen numerous attempts made but most of them are farcical.
Numerous attempts? Really... pray tell which official investigative body did them?
