Sergei Magnitsky, who was thrown into a Moscow jail in 2008 by the same officers he accused of tax fraud, was just convicted of tax evasion. Magnitsky died in his cell a year after his imprisonment, and the United States passed a law in his name. The Magnitsky Act bars anyone who was part of his political persecution from getting a visa to the United States. This led to the recent ban on adoption of Russian children by US parents. Now, Magnitsky has been convicted, sending an even stronger signal to would be dissenters in Russia.
