Let's assume for the sake of argument that he did commit suicide. The next question I would ask is "why would he do that"?

When airplanes crash!.....at that point the whistleblower had passed away in what looked like a suicide. But how did Boeing manage to pull that off? Join us for the next hour as we explain the science behind involuntary assisted suicide! We'll be interviewing putin corp's CEO Putin, who is an expert in these sort of things but too old to die by hanging.

It's too bad he didn't write a short letter saying the same thing and give it to her for safekeeping. As of right now all we have is her word. I'm hopeful that she'll testify.

Makes me wonder, how much does a professional hitman pay troll factories for white washing the crime with "but how do you know it wasn't a suicide", specially the ones that are equally professional about it not being flagrant? How much does it compare to cases in Russia for people suiciding out of windows with multiple gunshots?

When something isn't clearly black and white, without the facts and investigative research, continuing to discuss it usually makes it end up becoming a 50-50% grey area that grossly distorts as much as a completely black and white presumption would. In those cases, the initial "gut feeling" impression and the general education and awareness of a person involved may end up corresponding more to the reality, specially in cases actively trying to suppress the truth.

"Boeing", a non-living fictional mythos that has been accepted as a "person" so that the industrial revolution could be fueled, did not kill him. But there were plenty of psychopaths with power and influence who would have been affected by his deposition. some who've also been spearheading expansion into countries where dealing with and coming to compromises with its lowest ethical lowlifes (some of them also being potential or existing customers) would have been a necessity.
