What's the truth?
The sad thing is that there is so much obfuscation that the families and friends of those who were murdered, most probably by Russian affiliates and almost certainly by mistake, will never be 100% sure who it was who "pulled the trigger" and those who were murdered will never get the justice they deserve.
It is a shameful state of affairs and I hope that one day those who were responsible, including the leadership, rue the day they tried to hide the truth
