That makes his later statements the odd man out, and thus the version that should be discarded.
So, the majority is always right? Is that what you are saying?
I'll put it to you the way I put it to ....:
You have a guy who gives out one story soon after the fact. 2-3 decades later, he starts telling a very different, more involved (and jucier) story about the same event. You know that the other witnesses to the same event told a story that was consistent with the guy's first story, but contradicts his later one. The question to you is, which of the guy's two stories do you choose as most likely to be correct?
