On the chilly, clear afternoon of February 24, 2022—the day Vladimir Putin’s forces launched their full-scale invasion of Ukraine—a handful of Russian opposition politicians gathered in front of Saint Petersburg’s palatial Law, Order, and Security building. They had come to officially request permission to hold a rally opposing the war, which they knew would be denied. Among the group was Marina Matsapulina, the 30-year-old vice chair of Russia’s Libertarian Party. Matsapulina understood that the gathering was a symbolic gesture—and that it posed serious risks.
