In spite of public perceptions to the contrary, especially violent crime in Italy is low according to statistical indicators in comparison to most other European countries. Italy is, however, widely known for the diversity of internationally recognized criminal organizations which have operated for generations in the country and abroad, like the Italian mafias, the Camorra, or the Cosa Nostra. These organizations are responsible every year for a number of severe offences ranging from bribery and corruption to homicide and other grave acts of violence.
Petty crimes such as pick pocketing, theft from parked cars, and purse snatching are serious problems, especially in large cities. Most reported thefts occur at crowded tourist sites, on public buses or trains, or at the major railway stations.
