So what exactly is the protocol when there are two emergency vehicles on the road? Apparently, in this state trooper's mind squad cars are dominant over all. He is now under investigation for this footage of him stopping an ambulance. Not only was a patient in the back of the ambulance, but his attitude is just way out of control. I'm starting to think police officers need to be required to have sensitivity training so they can do their job which is to protect and serve; not abuse and belittle.
