Seriously though, Putin needs to stop killing dissidents. It is ridiculous. The bravest journalist in the country, Anna Politkovskaya, was also offed by Putin in October. She had previously been poisoned during the Beslan hostage situation so that she could not report on it. She was a hero to those who value a free press. Litvinenko was investigating her death.
Democracy is a farce if dissidents are murdered.
