There is no proof that any of the evidence has been manipulated or falsified by the JIT or Security Services of Ukraine. In order to find out the cause of the crash, the Joint Investigation Team investigated all human remains, personal belongings and wreckage of the aircraft found in the vicinity of the disaster site. The traces were secured and investigated and compared by experts. In addition, the JIT sought and heard witnesses and experts, analysed radar and satellite images, assessed large amounts of telecom data such as intercepted telephone conversations and analysed big data.

The results of the investigation of the Joint Investigation Team are clear: flight MH17 was shot down by a missile from the 9M38 series, which was launched by the BUK TELAR system. The system was transported from the Russian Federation to an agricultural field near the city of Pervomaiskiy in Eastern Ukraine, from where the rocket was launched. After firing, the system, with one missing missile, returned to the Russian Federation. On May 24 2018, JIT announced in its conclusion that the Buk belongs to the 53rd Anti-Aircraft Missile Brigade, a unit of the Russian armed forces in Kursk, Russian Federation. The public hearing on the incident started on 9 March 2020 in the Netherlands.
You can see other examples of pro-Kremlin disinformation on the MH17 case in our database, such as claims that JIT tampered with the evidence; that the plane was not downed by a BUK missile, but rather by a Ukrainian fighter; that the plane crash was triggered by an explosion on board; that the trial in The Hague is not justice but information warfare; that Moscow-supplied radar data was rejected; or that the MH17 crash was planned by Ukrainian, American, and Dutch intelligence agencies.
The last narrative that the West is "depraved to the ground" is recurrent. The suggestion that this "depravation" might let JIT fabricate the evidence and somehow influence the trial, is a conspiracy. The lawyers of the defendant Oleg Pulatov challenged the accusation in all possible ways. Thus, they asked to investigate evidence provided by the Ukrainian dispatcher Carlos. who "saw" a military jet next to Boeing. "Carlos" existed only in form of a Twitter account which was later renamed and deleted. But the argument of West's depravation has not been advanced at the MH17's trial by anybody and therefore is irrelevant.
