Yeah sure. The first guy alone in a car saw 4 guys in a truck and started crap with them.
Then the sheriff decided to jump in and help him out. That detail tells me who was biligerent and who wasnt.
It was a justifiable shooting in my opinion and likely in the opinion of any who witnessed it, however it would have been odd for such a confrontation to have occurred in front of a Deputy Sherriff, wouldn’t you say?
