I watched it as well. I don't have a strong opinion on what actually happened, but the details in the video of how LHO came to be employed at the book depository and his movements in the days preceding the assassination make it seem pretty improbable that his position there and the assassination were part of some carefully coordinated plan. For example, if there were actually multiple gunmen in different locations, who all fired within a few seconds, they would have to have had some way to coordinate not only the fact that they would shoot at the motorcade that day, but to precisely synchronize exactly when they all fired. How would they do that? Did LHO even have a watch? Were there other gunmen sitting around somewhere with their guns ready and on target and fingers on triggers, ready to fire within a split second of when some other shooter fired? I would also note, I've watched training videos on how to respond to mass shooter situations. One of the main points is to discount any claims of additional shooters in other locations until you hear shots yourself. It seems it's quite common in mass shooter situations for witnesses to falsely report additional shooters in other locations.
