I think it is pretty well established that all track and field athletes take performance enhancing drugs. The reason why is simple. If you do, your performance will be enhanced and you will win. If you don't, your performance will not be enhanced and you will lose.
I don't know if it is any worse that the government is in on it, as opposed to the U.S. model where it's every athlete for him/herself.
I remember a famous quote from an American weight lifter who was about to go up against the Russian champion in the Olympics. "Now we'll see once and for all who has the best pharmacists!!!"
No, I don't think it well established at all and I think that is a slur against clean athletes in the sport. There are many athletes (from many countries) who do not have one test, suspicious blood profile, avoided test or rumour darkening their names at all and to just assume that they 'must be at it' is a calumny that is unfortunately precipitated by the dreadful actions of a large percentage.
The report was commissioned with a narrow mandate to look at Russia because that was the country which had allegations made against it in a German TV documentary. They were trying to see how accurate the documentary was and so to paint it as some awful conspiracy to 'get Russia' is ridiculous.
It claimed Russian athletes paid 5% of their earnings to domestic doping officials to supply banned substances and cover-up tests, while athletics' world governing body the IAAF was implicated in covering up the abuse. A former anti-doping official (from Russia!) as well as testimony from Russian athletes was in the programme. Were they supposed to ignore this?
As has been said, non-Russian officials from the IAAF have been implicated and the only reason that more about this is not in the report is that there is a criminal investigation happening.
The report says that there was intentional and malicious destruction of more than 1,400 samples by Moscow laboratory officials after receiving written notification from Wada to preserve target samples. That isn't just coaches colluding with a few athletes to dope or a few rotten apples. That is systemic corruption.
So, although unfair to clean athletes in Russia, I can understand why they've called for a ban on Russia taking part in Worlds and perhaps the Rio Olympics. I think they are convinced that only a real sharp and obvious shock like that will change the system.
