It's interesting that even in US papers, the sudden trend of Russian oligarchs to become suicidal or murder-suicidal overnight is largely reported at face value, at best giving the context about how suddenly and frequently it is occurring.
Most mainstream press won't report things they can't prove. When they report on a Russian journalist falling out a window, they will usually mention that lots of opposition journalists have fallen out of windows and let readers draw conclusions, but we still have absolutely no direct proof they're being assassinated. I think news consumers have started to change their expectations and just really, really want pat answers fed to them rather than reading about what we actually know.
