Russian riot police officers detain Alexei Navalny, a prominent anti-corruption whistle blower and blogger, center, while he speaks to protesters gathered near the presidential administrations building in downtown Moscow early Tuesday, a day after Putin’s inauguration. Vladimir Putin took the oath of office in a brief but regal Kremlin ceremony on Monday, while on the streets outside thousands of helmeted riot police prevented hundreds of demonstrators from protesting his return to the presidency.
