And now the report that a radiation trail all the way back to Moscow has been discovered on 2 British Airways airliners.

Did you miss something? If the Russian SVR was going to bring the poison into the country they would have done so in a diplomatic pouch, and it would have been absolutely untraceable.

The implications discussed later in this thread are that the Russians wanted everyone to know where it came from. That is the intimidation factor. Which was also theoretically enhanced by the type of poisoning utilized. (IE - Putin don't care what you and I think anymore. He apparently has a nuclear genie up his sleeve.)
