Here is video of former Russian KGB agent Alexander Litvinenko speaking at London's Frontline club on October 19. Litvinenko's accusation: Russian President Putin had to have sanctioned the October murder of Russian investigative journalist, Anna Politkovskaya. Now, Litvinenko is also dead -- the 43-year-old died last Thursday about three weeks after ingesting the rare radioactive toxin, polonium 210. His illness took hold on Nov. 1, shortly after he ate at sushi bar in London. British police are currently calling Litvinenko's death "suspicious."
