Don’t you think it’s strange he goes into a stance, lifts up his gun and THEN we hear shots?? Unless he is responding to gun flashes he sees coming from the hotel? I just think it’s very strange why he would do that, even if he saw the gun flashes, I would think he would be more interested in ducking than returning shots with a handgun so far away, plus it doesn’t look like he is aiming at the hotel.
No, I don't think it's strange at all, because that is such a short video clip, how do we know that the shots heard on the video are the very first shots fired? It took a minute or two for people to even realize they were under gunfire, so that may have been the second, third, or forth group of shots. Clearly the audience is already in panic mode when the video begins. And the cop is wearing a safety vest because he was probably originally pulling traffic control duty for the event.
