I examined the video frame by frame.
At nine seconds, Yellow Hat is walking swiftly and calmly through the crowd of thugs blocking access to Milo’s speech, and no one pays him any attention. He appears to be just another protester helping block access.
At 17 seconds Bald Man suddenly starts running towards him, and Yellow Hat abruptly starts backing away
At 19 seconds, a big yell goes up from the crowd. Yellow Hat appears to be being beaten up by the much larger Bald Man, or possibly more than one much larger man, and is fleeing, dodging, and zig zagging.
He is trying to evade Bald Man, and Bald Man is pursuing. It looks like some more people are joining in to cut off Yellow Hat’s escape.
At 26 seconds, Yellow hat is not facing towards Bald Man, who is right behind him in hot pursuit, but rather facing towards another man who appears to be moving into the path of Yellow Hat’s escape, so that Yellow Hat is trapped between Bald Man whom he is fleeing, and people moving into his path. Possibly several men are moving to intercept Yellow Hat. One man is advancing towards him hands outstretched as if to grab him, another hits him with a piece of cloth, perhaps a crumpled up banner. At 27 seconds a shot rings out. Bald Man falls, and Yellow hat reverses course, paying absolutely no attention to the fallen Bald Man, and retreating from the man he was facing when the shot was fired. Yellow Hat runs towards a group of left wing banners.
Either someone else shot Bald Man to take the pressure off Yellow Hat, or Yellow Hat shot Bald Man while glancing at him out of the corner of his eye in order to give himself a path of retreat. Yellow Hat did not look at Bald Man immediately before, during, or immediately after the shot, yet his reversal or course indicates he was aware that Bald Man had suddenly ceased to be a threat, and that he was now ignoring Bald Man because he had far more urgent problems.
Immediately after the shot, we see a big bunch of people with black masks over their heads and faces run from behind the camera towards the place where Bald Man was shot. Black masks being a pretty good indication of bad intent. Whether by accident or design, Bald Man had been chasing Yellow Hat towards the place the black masks appeared from. To the left of camera, everyone starts looking at the place the black masks came from, like there is something there much more important than a mere shooting.
In conclusion, leftie on leftie violence. Either Yellow Hat shot Bald Man in self defense, or someone else shot Bald Man to take the heat off Yellow Hat, fearing Yellow hat was about to suffer grave harm, possibly at the hands of the black masks. Probably Judean People’s Front versus the People’s Front of Judea. What do you expect when you hang out with violent thugs? Maybe everyone involved was a bad guy, but the one who got the bullet was the one who attacked first, unless a different bald man got popped in the confusion. Looks like justice on the face of it. Back in the sixties and early seventies I noticed that radical left organizations had a mysterious unfortunate mystery death rate similar to that of Clinton Associates.
