“Robbery in Serbia: After Turkey, Serbia undoubtedly has the largest contingent of robbers in the Balkans. The majority of robbers, called Haiduks here, are recruited from escaped convicts for whom the road seems too long or too harsh; a smaller number come from those who believe themselves to be unjustly persecuted by the authorities and therefore want to take revenge on their pursuers when the opportunity arises. “
