I read the entire 27 pages of this thread and would like to add my .02 cents;
Red_zed made a lot of valid points, and even though initially it may seem as he is siding with the bikers, after reading the entire argument he is just playing the devils advocate and looking at the case objectively just like the DA will, or at least should.
No questions that the popularity of this case will have some influence on the events that will follow...
It seems like the consensus here is that the RR driver is justified in his actions, and I also concur with this.
A few things that I would like to point out;
1. You can obviously see in the original video 12+ other go-pro's and other cameras on the helmets, it is ironic that all of the cameras do not have the entire footage or how this was initiated.
2. The fact that the OP (biker who posted the video) took down all 7 of the videos of the same gang behaving recklessly on that same day is also another questionable move.
3. 911 call evidence with the RR driver being directed by dispatch to get of the highway to the nearest police station.
just like Red_zed say I would do my best to not get caught in a similar situation, but life happens and some things we can not control.
My only option would be to defend myself and my family, I would also drop the hammer on the bikers in front of me.
