[…] Here is what I think where the areas are located where the bullet that hit Trumps ear could have come from when extending the lines from the first post above. The areas in-between the two long green lines correspond roughly to the possible angle areas in the first post above, where I think it is most likely for that specific shot to have come from, while not taking into account where that specific bullet might have landed after it hit Trump. The short dashed black lines represent the areas that are increasingly less likely IMO, increasing in unlikeliness the further you go from the long green lines toward the long black lines:
That is why I think, if we just take that one specific bullet that hit Trumps ear into account, until the point it hit Trumps ear, that the 2-story building (left of Crooks building and behind Crooks building, in that picture) is more on the unlikely side for that specific bullet: Or more specifically, everything left of the utmost right window of that building. In other words: only the utmost right window of that 2-story building seems in the realm of good likelihood, to me, for that specific bullet.
