There is a s**t load of propaganda. I mean if that guy was a double agent, can you really blame Russia for getting rid of him? Isn't that protecting national interest? Wouldn't UK have done the same? The only difference would have been that UK would be much more discreet. Also like you said, Saudi Arabia literally gets away with murder everyday. But none of that come in the media. Only selective content approved by certain people will ever get to the eyes and ears of the general public. Unfortunately that's just the times that we live in.
