We know that the Russkies took credit for it and even bragged about the murder on their social media, before they realized it was a Malaysian airliner, and thus they took it down off their official pages, including videos they took of the aircraft being fired upon. Afterwards, they first claimed that the airliner was filled with dead bodies drained of blood and was sent by the Ukrainians to sully the name of Russia's elite forces. After this, they blamed a Ukrainian ground attack jet of magically having the ability to fly 10,000 feet above its maximum altitude without weapons to shoot the airliner down-- the Russians even produced fake satellite imagery of the exact moment the missile went flying from the SU-25 (because Russians are very very stupid people in general). This led to a Wikipedia edit war as IPs from Russia rushed to increase the stats of the Frogfoot to make their claims ring true. This all climaxed with the BUK system responsible being filmed fleeing Ukrainian territory and being moved back into Russian territory. What you call "extraordinary ability" by the Russkies to play with information is really more like retarded monkeys throwing crap at the wall hoping some idiot will get deluded.
How do you know all those “slip ups” arent just more disinformation? You can make anything appear to be from anywhere these days.
This is poker. Not checkers.
