Morphing memories (as I am defining them) are ones that change character entirely. I am not interested in memories in which small details might be misremembered because that is normal for us humans. For an example of a morphing memory, as I define it, if Buell Frazier had really seen LHO walking up Houston Street after the assassination, I don’t think that there is any way he could have forgotten that when he swore that he didn’t see LHO after 11:00 am when he made his affidavit on 11/22/63.
Also, the WC testimonies included questions by the investigators which were meant to bring out additional details that might not have been included in earlier statements. So, that type of thing isn’t really a morphed memory, as I am defining it.
