You're right about the burden of proof being on the prosecutor, but one small point: It would have been the State of Texas that prosecuted Oswald, because killing or attempting to kill the President wasn't a federal crime in '63. That's why the state needed its own autopsy. Had Oswald survived to stand trial, the lack of a state autopsy might have hampered prosecution. The Texas authorities were absolutely in the right in this instance.
