I bet there is no audio. It would be interesting to know if the “first shots” were off camera.
I think the CNN voice-over was a little hyped up in terms of what this looked like to me. Of all the players in the thing I could see, only one of the bikers I could see had a gun, and it was pointed at the ground most of the time.
My conclusion is there was a fight between two groups of bikers. That’s pretty much it.
