"Traces of the isotope were later found in many of the same places where the two alleged killers had visited: The hotel's bathroom, their hotel room, a board room where they conducted an earlier meeting and the plane they traveled aboard."
We're not talking about traces of carbon or lead, here.
Perhaps but that's not evidence.
>There is no doubt about Lugovoy or Kovtun's involvement, but directly or indirectly Putin is responsible for his agents running around poisoning people with plutonium.
That's not evidence either. Besides, they were ex-KGB / FSB agents.
>The fact they are refusing to extradite them is telling as well.
Let's reverse this. Would Obama agree to extradite a Republican ex-CIA agent with powerful friends who flew to Moscow and killed Edward Snowden without his knowledge?
Can you imagine what the political fallout would be if he did? He'd be characterized as a mixture of powerless, hypocritical, traitorous and anti-American all at once by both friends and enemies. Political suicide at worst; own goal at best.
The motivations described are certainly insufficient to withstand scrutiny.
"Finally, there was undoubtedly a personal dimension to the antagonism between Mr Litvinenko on the one hand and President Putin on the other. The history between the two men dated back to their (only) meeting in 1998, at a time when Mr Putin was the newly appointed head of the FSB and Mr Berezovsky and Mr Litvinenko still hoped that he might implement a programme of reform. In the years that followed,Mr Litvinenko made repeated highly personal attacks on President Putin, culminating in the allegation of paedophilia in July 2006"
That is from the report. Call me a Putin-apologist, an agent from Olgino, but these motives look like garbage. There is an entire industry of "making highly personal attacks" on Putin and blaming all kinds of things on him. The name of these "Putin's critics" is legion, they have been doing it for more than a decade, and they've had zero success... that is, of course, if by "success" you mean making Russians believe what they say, and not just selling shocking stories about the darkest secrets of the KayGeeBee to British tabloids...
