This is hugely important context to always keep in mind. The fact that MBS had managed to bamboozle the western media into fawning over his token "reforms" prior to the Saudis brazenly murdering Kashoggi was a disgrace.
It's telling that the media only really started caring about Saudi governmental corruption and criminality after one of their own - a fellow pundit who traveled in elite western circles - was grotesquely killed. MBS presumably had good reason to believe he could get away with murder, with Kashoggi being the exception that proves the rule.
