This is seriously incredible. The man with the camera is Vladimir Putin, then with the KGB and just starting his climb to the top, here pretending he is just a normal soviet tourist who just happens to have come by at the same time as the American President. From the story:
While on his visit, former Russian Premiere Gorbachev directed Reagan towards a number of “tourists” who then asked him politically charged questions about human rights.
At one point, Pete Souza, the photographer who snapped this picture, turned to the secret service and commented, “I can’t believe these tourists in the Soviet Union are asking these pointed questions.” The agent replied, “Oh, these are KGB families.”
Trust and verify! What fools they must take us for.
