Did Vladimir Putin "Putey-Put" The Polonium 210 In Former Super Spy's Sushi?

[Ed. note: Putey-put, as you may sadly recall, is President Bush's "pet" name for the Russian czarpresident. Which makes me wonder what other world leaders use as a "pet" name for Bush.]

The widow of Alexander Litvinenko, the former Russian KGB super spy who came up through the KGB ranks with Putin and became very critical of the Kremlin in general and Putin specifically, points the finger at Putin as a likely suspect (although unlikely the person who actually did the deed directly) in her husband's death by Polonium-210.
