There is Nothing "logical" as to the movements that have been attributed to a Vertigo suffering, overweight, 58 year old man. Sitzman's narrative checks all the boxes and was her 1st in-depth/detailed interview. The interview was also conducted by a very respected individual. The interview Tink Thompson did with Sitzman was Far more detailed than Anything that was ever done with Zapruder. This would include Zapruder's testimonies.
