Looks to me like the first shot missed.Replied to you in another thread with this:
I hear the initial shots, the first of which seems to strike Trump. Then a volley of shots, presumably return fire. The video of the agent on the roof shoes that he balked during the first three shots. I don’t believe he actually fired. He balked.
Then, it seems there is a final, single shot, 8 or 9 seconds after the volley of multiple shots.
Well, at least we know interpretation of the event isn’t straightforward- different views here.
