Maybe because white guys arent pointing the long guns at cops.
Mostly true, but more true is that when a white (or any race) guy with a gun points said gun at the cops and gets shot by the cops, other white guys with guns usually say, "Dumbass! What the hell was he thinking would happen!?! Better nominate him for a Darwin Award!"
This is neglecting now too frequent edge cases like "cops get warrant for wrong house, homeowner dies in ensuing firefight" or "child with obvious fake gun gets shot by police"
