Perhaps I am forgetting reading it (or, perhaps it was never mentioned in its report nor volumes):
When witnesses testified in-person to the "WC" commissioner's, were all/some/none of their testimony audio tape-recorded?
If all or some of their "WC" in-person testimony was audio-recorded, have these audio recordings also been made available for researchers? (IIRC, Mrs. Kennedy's very short testimony was audio-recorded. Has her audio-recording been made available to researcher's?)
Same question for when all witnesses who did not testify in-person to the "WC" commissioner's, and he/she, instead, gave only summarized-later by the FBI-SS-Dallas police-etc interviewing Agent, Agent-written/typed-up summarized-statements to the FBI-SS-Dallas police-etc interviewing Agent.
