Sicily, the rougher-edged, thuggier brother to happy go lucky mainland Italy, is famous as the birthplace of the mafia. But mainland Naples – a gorgeous UNESCO site – is equally infamous as the home of the Camorra, a criminal organization dating back to the 18th century. Despite the best efforts of Italian authorities it continues to thrive here, and as it consists of clans instead of a structured body there tends to be lots of fussing and feuding. Thus in the past decade there have been a few hundred street-killings, right in broad daylight. Adding to the danger, Nigerian and Albanian gangs are now part of the scene, and fight for control of the booming drug and sex slave market that supplies the rest of Europe.
