I'm sorry, but what you're saying is utterly ridiculous. ==
You simply do not know who Berezovskii is. He is well known swindler and provocateer. He can do everything if it is in his favor.
Those oligarkhs are all the same. Khodorkovskii ordered hits of his competitors and the major of sibirian town. Gusinskii stole hunderds millions of dollars. Berezovskii was the main cofounder of LogoVAZ well knownb swindler scheme in Russia. He is wanted by the prosecutor office but your goverment covers him from justice.
You patriotism do not allow you to admit that Britain gave her shores to outright criminals.
I see a lot of hysteria and nonsense - a lot of completely illogical rubbish out of Putin's defenders. We could have a videotape of Putin shooting puppies in the head with an automatic and you'd put the blame somewhere other than where it lies.
