Yeah, an *unprovoked attack* while he was intent on committing an unprovoked attack with likely a high power firearm, against a dumb animal with horns and hooves.

Actually they are not so dumb. Once they know you are tracking them or are wounded, they will double back and ambush you. Leopards have been known to do the same thing. Peter Capstick “Death on the Dark Continent “ wrote of this trait. The author Theodore Waldeck(sp?) was treed by one when hunting for meat for his camp. His gun bearer drop his rifle and climbed a tree as did he. It was a great story. Cape Buffalo are not to be trifled with. IMO regards
