Continuing the discussion from Stabilized, interpolated, panoramic footage of JFK’s assassination:
Was he 81 meters from the ground floor? 81 meters down the road from the center of the building or the corner? Then you have to take the hypoteneuse of the right triangle with short side = the distance from the building to the center of the lane the care was in and long side = those 81 meters and use that value as one side of a right triangle with the other side the distance from the ground to the window then take the hypoteneuse of that triangle to get the distance of the shot. I don’t have distance from door to center of the lane, or I’d calculate it out. In any case I am sure the shot was more than 81 meters. Not arguing against Oswald’s ability/non-ability to make the shot, just making the mathematical point - it’s so important to be accurate when discussing forensic stuff especially.
