Do you grasp the difference between speculation and definitive evidence?
``I think'' that you were actually the second gunman who was on the grassy
knoll on that crisp November day in 1963 back in Dallas. So should we
lock you up?

No, it's speculation, and no even very substantial speculation.

He didn't say that he actually knew of any.
