Also...people will believe what they want to believe.I just think there was and still is definitely a cover-up and there never was a genuine investigation.
We won't know every last detail. Some things are unknowable.What we can say, based on the evidence, is that Saint Patsy murdered two people on 11/22/63 beyond any reasonable doubt.There are those that will never be convinced that the accumulated evidence is genuine. In essence their position is; the evidence isn't real, therefore the case is unsolvable. It's safe to say they'll never know what happened.Which is why the debate will go on forever.
I understand there are psychological studies which give some insight to this.
