I predict if you get any answer at all, it will be a variation of one of the following:
- A nonspecific reference to Bugliosi's "53".
- A nonspecific reference to "mountains" of evidence
- "Nothing would satisfy you people other than a video of Oswald in the act"
- "It's in the history books"
- "What's your evidence that Oswald didn't do it?"
- "Name your shooter"
- "Prove there was a conspiracy"
Pretty much anything other than an actual answer to the question you asked.
