Yeah, and the SS Agents in the Queen Mary all said they reacted IMMEDIATELY. But the photographic records indicate otherwise. And an apparently similar situation with Victoria Adams. When the physical evidence contradicts the witnesses memories, I tend to believe the physical evidence.
With regard to Sitzman, we are talking about a Sequence Of Events that YOU are claiming she made. Sitzman NEVER Mentioned doing any of the stuff that YOU are attaching to her. Sure, the internal "time clock" that a person has can be a legit issue, but their recollection of their PHYSICAL ACTS/MOVEMENT are an entirely different matter. And there is NO Photographic or Physical Evidence putting Sitzman on The Cement Walkway, or The Steps. NONE. This is ALL speculation by YOU
