"On the poisoning of ex-spy Alexander Litvinenko in London, Mr Putin said he did not believe in conspiracy theories."
This tell us something worth remembering about the cant term "conspiracy theory", what it's good for, and what kind of people routinely use it as a blunt but dependable weapon.
"Mr Litvinenko was a vehement critic of Mr Putin. Mr Putin said Mr Litvinenko "did not possess any secrets" that could have damaged Russia. "
Oh, really? So why did they confiscate his books?
Allegations against the Russian Government
Litvinenko alleged that agents from the FSB co-ordinated the 1999 Russian apartment bombings that killed more than 300 people, whereas Russian officials blamed the explosions on Chechen separatists. This version of events was suggested
earlier by David Satter, and Sergei Yushenkov, vice chairman of the Sergei Kovalev commission created by the Russian Parliament to investigate the bombings. However, Litvinenko provided many new factual details in his book. In December 2003 Russian authorities confiscated over 4000 copies of the book en route to Moscow from the publisher in Latvia.
