For this reason (and others also), they can be expected to have a quite different concept of "truth" than we in Western countries have.
Keep in mind that in the aftermath of the intentional destruction of EgyptAir flight 990 - by its copilot - the Egyptian government asked the NTSB to investigate the disaster. When that investigation began to point to the actions of the cabin crew as the probable cause of the crash, the Egyptians became very unhappy, started their own investigation, which followed "a completely different line of thinking," according to aviation journalist William Langewiesche, as reported in the Wikipedia article on the matter.
The results in the Egyptian pointed in many directions at the same time, most involving mechanical failure of the Boeing 767 aircraft.
In the words of reporter Langewiesche:
"It seemed to me that they knew very well that their man, Batouti, had done this. They were pursuing a political agenda that was driven by the need to answer to their higher-ups in a very pyramidal, autocratic political structure. The word had been passed down from on high, probably from Mubarak himself, that there was no way that Batouti, the co-pilot, could have done this. For the accident investigators in Egypt, the game then became not pursuing the truth but backing the official line."
Oh @#$%, same stuff, different day :/
Why all the obfuscation, stonewalling, “look a squirrel!!!!!” from certain countries.
:(
I know of at least three other events where backing the official line became the game.
KAL007, TWA800...
