Were they sitting around chatting while holding a shotgun, was the shotgun in the truck, or did they purposely go get the shotgun to chase the guy? It is important to know at what time the gun left a case, a rack or the truck and get into the shooters hands. What were their verbal exchanges with the victim that could have caused him to believe he had to protect himself or die?
The shooters(redneck kkk types) were in no imminent danger. They had their eyes and camera on the guy. They called 911 and they were on the way.
At this point it became murder and I’d vote 1st degree murder.
