It is illegal to classify information for the purpose of covering up a crime.
I wonder if everyone that has seen the information and left it classified is culpable and could be prosecuted?

Good question, and we will probably never know because we will never see it.
First, you are going to have to convince the current population that killing JFK was a crime. Good Luck!
