Leonel Kaplan, an Argentine jazz musician, often has to travel abroad.
Before a recent trip to Europe, he went to a bank in Buenos Aires to change money and then went to get a haircut. Kaplan felt happy and relaxed and took the bus home after what had been an uneventful trip.
That, however, was about to change.
"As I get down from the bus, a motorcycle with two people wearing helmets cuts me off," he recalls. "One gets off and takes out a gun and says to me directly, 'Give me the 500 euros you got in the bank.' "
