Bingo.
Until there's some reason to question the police statement that the guy pulled a gun on the cop, there's no reason to assume otherwise.
White people do this "unnecessary shooting" narrative thing too, when their interests are engaged. Case in point...
I married into a family of criminals. Well, my wife's immediate family were straight, but almost all of her uncles, cousins and etc were career criminals, some of them very serious felons with ties to what passes for organized crime locally. You can imagine how awkward family get-togethers were.
One of her uncles had been killed by the police a decade before, and they still carried the torch of him being a martyr who was needlessly murdered. As the story goes, he was drunk and disorderly and pulled a knife on the cops, who shot him from twenty feet away when he "charged". The family says he would never have actually stabbed anyone, why did they have to shoot him six times it was just a small pocket knife, he was drunk and they should have taken that into account, etc etc.... then they tried to bring ME into it and ask ME if I would have shot him!
I said "Whoa, hey.... I wasn't there, I don't know what happened exactly, so I can't really say what should or should not have happened." That answer didn't satisfy them much, but it was a much better answer than the raw truth... which would have been "if he'd charged me with a knife as the cops said he did, I'd have lit him up too." :doh
