So I went looking and found this video which shows 6 different clips from video taken. I was wrong on a number of things. It wasn't a sport bike chasing, looks like a standard. The truck actually hit the jeep on the driver side causing the damage and flat tire, it does not appear that the Jeep hit a jersey barrier. Another thing that really stood out to me is the other guns in the protest. At 2:12 in this video there is a very obvious gun from someone who was not the shooter, but looks prepared to shoot. I don't know how common guns are at these type of protests, but it seems like an incredibly bad idea to have your gun there and these people seem like they may be quick to draw. Or at least quicker than I think I would be in that same situation. Anywho; sorry for the earlier misinformation.
