Blake changed her story after coaching and one 0bama supporting witness with a memory she claims to have is not enough to prove anything.
That's a pretty broad based and vague rebuttal. She changed her story about the date? She changed her story about the Visit? She changed her story about the Diaper?
I've personally watched the video and read the interview, so I would be very interested to know what she could have changed her story to that would revoke what she had already said. What is it that she changed her story about?
In any case, I believe there is more than one person that claims to have seen Stanley in Seattle Subsequent to August 1961.
