There could never be a true trial for LHO. Jack Ruby made sure of that. However, the rules that the courts have in place are there to try to help insure that a fair trial takes place. I think that our opinions could possibly be made more fair if we at least consider what the courts would have done if LHO had lived to go to trial. Here is another snip from the Fifth Circuit:
As I told you earlier, it is your duty to determine the facts. To do so, you must consider only the evidence presented during the trial. Evidence is the sworn testimony of the witnesses, including stipulations, and the exhibits. The questions, statements, objections, and arguments made by the lawyers are not evidence.
The function of the lawyers is to point out those things that are most significant or most helpful to their side of the case, and in so doing to call your attention to certain facts or inferences that might otherwise escape your notice. In the final analysis, however, it is your own recollection and interpretation of the evidence that controls in the case. What the lawyers say is not binding upon you.
People can speculate about what might have happened all they want to for as long as they want to. Many conspiracy oriented books have been sold and read based on speculations. But that is all they are, speculation (which is not allowed in the courts).
