I, too, think this is staged. It doesn't pass the smell test for me. I can't prove it - just a feeling. There are a few things that seemed to do it for me. The BMW driver seemed to continue to antagonize the supposed BG's and lured them to a remote location. If he would have shot and killed them it could have been considered by a prosecutor as 1st degree murder. Not to mention that that BMW could run circles around the Tundra enough to make the BG's head spin. Plus the woman from the car was too cool about approaching the BG with the camera. There was not enough apprehension in her demeanor. She either has done this a lot before (having a criminal record?) or is a very bad actor.
Of course if it is real it should be used in carry classes as a "how not to" example.
