That's a good question. I'm glad you asked it. I'm particularly glad you brought up those 20 officials.
Shortly after Sergei died, they made a big deal about the fact that he died and fired 20 governors of different prisons around Russia. Of those 20 fired prison governors, 19 had nothing to do with any place that Sergei Magnitsky was held in detention, so there was no relationship between them and Sergei Magnitsky. The one who had been in charge of the prison where Sergei was held was reappointed deputy head of another prison several weeks later.
There have been no civil or criminal charges laid against any individual on this list of 60 people, and as I said before, a number of them, including the one who was most closely associated with his torture, have been promoted. It's now a year since this whole thing happened, and they've more or less said--informally, not formally, because they haven't concluded the investigation--that there is nobody who is going to be held responsible for the death of Sergei Magnitsky.
If you were to receive a visit from the Russian ambassador, he would say, “The investigation is ongoing, let it take its course”, but what he won't tell you is that some of the people on the ongoing investigation team are also some of the accused. They are running the investigation of themselves.
