Not what Lattimer, "Target Car" and the Haags claimed to be doing anyway. They were duplicating a Carcano bullet passing though replicas of humans to see if slowing and tumbling of the bullet would result in a condition similar to CE 399. That's what rational people do in a criminal case with a mystery; they assume nothing until they've conducted experiments and tests.
Doing tests to see if something is
possible doesn’t solve any mystery. And it’s not true that they are assuming nothing. They are assuming that CE 399 was actually fired at the motorcade.
Can you prove he wasn't wrong in that regard?
No, and I’m making no such claim as to the provenance of CE399,
you are.
Feel free to present an alternative scenario that's more rational.
What’s rational is to say “I don’t know” when you don’t know something rather than making up a solution and assuming it’s correct until it can be proven wrong.
Many things in a crime case can't be proven conclusively or to an absolute.
I’m comfortable with a reasonable doubt standard. There isn’t an aspect of this case that doesn’t have grounds for reasonable doubt.
There's no time travel yet, and most events weren't captured on film. Human memory is fallible.
Agreed, but you don’t practice what you preach. You’re fine with human memory when it suits
your conclusions.
Reasonable people use common sense to assess the totality of the evidence.
One person’s “common sense” is another person’s unsubstantiated conjecture.
