First: Is "every redneck yokel and his dumb brother is allowed to own an arsenal" in anyway better than a government monopoly in that regard?
Second: This would of course need properly selected and trained policemen, not those trigger-happy yokels that the US uses instead.
My position is from a country where "Police Brutality" is seen as an American or other third world country thing. We don't allow every random idiot to own a gun. We have properly trained police. We therefor also don't have issues like Uvalde and George Floyd. For an American, it is hard to draw a straight line between those factors, but in the rest of the civilized world, it is the standard.
