For many years, Russia’s Service for the Protection of the Constitutional Order and the Fight against Terrorism (SZKSBТ), also known as the FSB’s Second Service, has effectively functioned as Russia’s version of the Gestapo — a secret police force responsible for domestic repression and terror. It was officers from this very service who poisoned Alexei Navalny, Dmitry Bykov, and Vladimir Kara-Murza. Agents of the Second Service were also responsible for tracking Boris Nemtsov in the final weeks before his murder. Furthermore, they stand behind the killings of political analyst Nikita Isaev, journalist Timur Kuashev, and activist Ruslan Magomedragimov. In an exclusive interview with The Insider, former FSB Second Service officer Alexander Fedotov reveals from within how the service operates. Fedotov offers a detailed look at how Navalny’s poisoners rose through the ranks and explains how the FSB continues to build a system that maintains total surveillance over opposition figures and activists, whether those enemies of the regime are inside Russia or abroad.
