Everybody but the girl should go to jail. The BMW driver should have just reported the reckless drivers, and left it at that. It appears he was trying to make a citizen arrest, while legal in most states his driving to catch them was not. The girl did nothing wrong, but react to a threat to the drivers life, thank the lord she was armed, who knows how it would have turned out otherwise. I cannot condone anybody driving like reckless fools, even less after being the fool adding battery to the mix. Hope they are caught, and spend a very long time in jail, as well as having their bikes seized.
This goes back to do stupid things win stupid prizes.
