I just came across an explanation for the location shenanigans this morning when reading the Russian press next to the UK press. I always do that with my morning coffee. A good approximation of what can be believed on first read is whatever is present in both - you bring up one on the left half the screen, the other on the right and mentally scratch out all the differences. In this case the more nationalistic bits of the Russian press are up in flames regarding the Dutch "falsifying the MH017 evidence".
First and foremost, they are working based on what is presented - what is presented to press does not equate to what is in the actual ballistic analysis and is not what we will (hopefully) one day see in court. As the full ballistic analysis from the full unedited commission report on the missile is still classified it is difficult to say if they are right or wrong.
Second, even if what they noticed is correct, they got the root cause wrong. It is not likely to be falsification, it is what we call a "f*ckup" - F... Again in Engineering which was missed due to severe case of confirmation bias.
