"The United States Congress and President Barack Obama enacted the Magnitsky Act at the end of 2012, barring those Russian officials believed to be involved in Magnitsky's death from entering the United States or using its banking system. In early January 2013, the Financial Times wrote that "the Magnitsky case is egregious, well documented and encapsulates the darker side of Putinism". In November 2010, Magnitsky was given a posthumous award from Transparency International for integrity. Magnitsky, according to the awards committee, "believed in the rule of law and died for his belief." In late 2010, international attention to the matter intensified, with the European Parliament calling for 60 officials believed to be connected to Magnitsky's death to be banned from entering the European Union, and the Parliament of Canada resolving to deny visas to and freeze the Canadian assets of allegedly involved officials. The EU Parliament also urged members to freeze assets of officials, while similar measures were under consideration in the United States. In October 2010, US Senator John McCain co-sponsored the Justice for Sergei Magnitsky Act, which would forbid entry to the US to 60 individuals named in court documents related to the Magnitsky case. https://en.wikipedia.org/wiki/Sergei_Magnitsky" The Magnitsky Act hit Putin where it really hurt. That's when he went kinda nuts, and started escalating his actions.
