From the Youtube video description
After forcing the truck to hit his car because of slamming on his brakes numerous times, the truck hits his car. Minor scratches to his car, the truck needs a new bumper and grill. Road rage much? He purposely forced an accident and gets out of his car and starts doing this. A real motivated Sgt disrespecting a fellow Marine who is in a wheelchair and the driver who is a civilian.At the End of the video you see him place his hands on the trunk, well that is because the MP’s pulled up and arrested him.
