Not when it can contract that out to the Saudi government then help them cover it up. But yes, your point is well taken. It was just more convenient to have MBS murder that particular Washington Post reporter, this time. But the other "enemies of the people" are on notice that they'd better watch their mouths and asses.
There is absolutely no evidence whatsoever that the US contracted out this murder to SA, or even approved it before the fact. Your post is warrantless speculation masquerading as obvious truth. This helps damage trust in your already fragile democracy. Please don't do that.
The US murders journalists.
