Interesting news this morning: Khasan Zakaev, one of the terrorist which organized and executed the 2002 attack against the Dubrovka theater in Moscow and an aid to Shamil Basaev was arrested in Crimea when he tried to enter from the Ukraine with false documents.
I very much doubt that Zakaev wanted to visit Crimea to enjoy the beautiful sights, sample the local cuisine or to relax on the seashore. Not coming from the Ukraine. Not with fake documents. In fact, I would argue that it is pretty darn obvious that if he took the huge risk of entering not just any Russian territory, but a highly monitored and secured one, he was there on a mission.
