You can learn a lot from studying timelines in a case, any case. It allows for a linear approach to events that’s similar to standing on the highest mountain and looking down. Everything regarding unfolding events is made clearer.
So what follows is the timeline of Lee Oswald’s weekends at Ruth Paine’s home from October to the last weekend before the assassination. It was chosen as there were so many sightings of Oswald at various locations, mainly the shooting range, on the weekends when Ruth Paine is maintaining that Lee was at her house on those days except for the last weekend before the assassination when he stayed at the rooming house. Perhaps she was not lying at all, if there is an impersonator in play. Warren Commission lawyers knew there were problems in Ruth’s testimony as so many people were seeing Lee at the Sports Drome Rifle Range when he wasn’t supposed to have been there. Eventually, they just had to let it all be.
Please note that on those days or weekends that Ruth Paine maintains that Lee was at her house, he is not supposed to be seen anywhere else, especially at night. Yet witnesses reported seeing Oswald at various locations from Dallas to New Orleans.
