And CIA under Obama administration killed Andrew Breitbart when he started talking about Podesta's closet (https://www.youtube.com/watch?v=CgBvPx4CvhI). But of course he died of a "heart attack" just like Russian journalists seem to do.
But yeah, it was just a coincidence. Only powerful people in Russia and China kill journalists. In the US, they just die of accidents and natural causes.
Yes, because it's tried and true and works for them.
