The exchange of prisoners is a rare event in international life. At least in peacetime. Prisoners selected for exchange can consider themselves lucky, tearing a large gain in the lottery. Imagine: yesterday - a camera, hopelessness and a long time ahead, and today, unexpectedly, as in a fairy tale - freedom, family, friends, maybe emigration, but still freedom! I would like to be glad for each exchange, regardless of his citizenship, the term of punishment and corpus delicti.
