"It is a crime. Evidence is usually withheld until a trial or enquiry.
The details of how Alexander Litvinenko was murdered did not emerge for months."

What absolute nonsense. Enough direct accusation has been made against Russia from on high by the great and the good to make any "fair trial" against Russia completely impossible. The whole thing has been prejudiced out of existence by over-hasty and clumsy pronouncements by anti-Russia ideologues. If you aspire to achieving fair judgement against the accused you keep ALL your cards close to your chest, not keep dribbling out bits of half-arsed, evidence-innocent assertions. There's been nothing new for over two weeks now except for febrile attempts at Putin character-assassinations, including accusations of Hitlerism against the one country that made more sacrifices than everyone else put together to defeat Hitler. Bloody disgusting.
