Rio de Janeiro, Brazil
There are few places in the world that offer so much physical beauty – both from the people and the landscape. Yet Rio is equally renowned for the staggering amount of poverty and related violence from powerful drug lords and street gangs. Generally those have been confined to the favelas or slums, but small time crime like pickpocketing has now been joined with the vogue practice of "quicknapping:" An intense, street-style kidnapping that involves a trip to the ATM or a bank instead of phone calls to relatives. Assuming you have enough cash.
