So, you've reviewed all the security camera footage inside and outside the embassy? Or, are you mistaking “no security camera footage has been leaked to the public showing this” for “none of the security camera footage shot shows this”?
I have footage of Trump and Hillary leaving a Motel together. Do you believe me? Why not - have you watched all the footage? Didn't think so...
(There's a web of trust so to speak, with journalism and investigative reporting).
At least you haven't caught me lying before, doesn't that count for anything?
Even most o the journalism prices don't mean much anymore. Here in Germany there was just a scandal of a journalist faking many stories, who had also won lots of prices with them (Claas Relotius). In some articles about him it was also mentioned that by now there is also a kind of "inflation" of journalism prices. I think they also serve the purpose of creating a fake aura of trust.
