If that's the case why would he care about this guy?
Or is Putin going to try to stay in office indefinitely?
Once he leaves Russian Premiership Vlad Putin intends to become the power behind the throne. This has been posted mnay times
“Putin, the 'big bad' of the KGB is BACK (if he ever left) and will kill you in any of thousands of rare and unpleasant ways if you cross him”.
Polonium? Man that is an expensive way to kill someone. Last price I heard on the stuff back in the 70s was well over $100,000 an ounce (or per gram? memory hazy on that point.) Anyway, there are less than three ounces of that stuff produced per year, world wide, and according to news reports, there was a lot of it spread around Litvinenko's haunts.
Its not something you can find laying around in the cabinet under the sink; I can’t find it listed in my 3000 page catalog from a chemical-elemental material supplier who sells darn near EVERYTHING, no matter how rare, dangerous and expensive. You have to have access to particle accelerators or nuclear labs to steal the stuff, and licences out the kazoo to purchase it... Only a couple of legitimate non-research industrial uses for it.
Yep, if there really is polonium involved, I’d lay money that Putin is DIRECTLY involved, and he wants people in the right places to understand that who, how and why it happened, and that he isn't playing games.
