http://www.youtube.com/watch?v=KluItc365hU&feature=popular Just a theory. Like a lot of officers, this one probably just got back from Iraq or something and is still in that "mode". Roughing up Iraqi civilians is not at all frowned upon. You pretty much have to do whatever is necessary to get them to understand that you are in control and they just need to shut the heck up. Stopping ANY vehicle is normal and if they don't stop, you shoot it. Maybe in defence of the cop; Seems like some PTSD to me. If I am wrong on this theory, than that cop is a real A** and needs to be behind bars.
