It seems to me that when numerous reliable witnesses independent of each other all say the same thing, that makes for a compelling case. Apparently Sean Johnson does not think so. I wonder how he would have gotten by if he lived in another age when there was no audio and video recordings, and people have to rely on witnesses and testimony.
Perhaps an analogy would be helpful now.
Imagine a church before a wedding.  2 members of the groom's family are waiting in the sacristy for the not-yet-arrived groom and his chum--formally the 'best man'--to "get him to the church on time". The celebrant priest departs briefly to check on some arrangements. While waiting by themselves, 1 family member tells the other: "I hope I'm wrong, but I have a really bad feeling about this. I fear that the bride is a really
bad choice: She's behaved like a self-centered b####--not even bothering to hide that--waaay too often since the family announced their engagement."
Later that day, at the wedding reception, the same family member offers an unreservedly
optimistic toast to the newly married couple, which, like other toasts there, is videotaped.
Years later, as the marriage tumbles downhill, the originally fearful family member is accused of being unsupportive of the wedding, by the other family member who was also in the sacristy before the wedding. (Whether or not the accused family member had any responsibility--of any kind--to act on his fears before the wedding is
not the issue herein.)  But the accused repeatedly avoids any straightforward answers.
No problem: It'll be easy to set the record straight: Just
replay the videotape of his
toast at the wedding reception!  That'll
prove whether he was really supportive of the wedding--or not.
Sooo, might there be any logical flaws in the insistence by recording-technology enthusiasts that that the videotape of the reception would provide
conclusive proof one way or t'other?
