The Netherlands legal system is based on the civil law system incorporating some French penal theory. While the rate of violent crime in the Netherlands is low, tourists are often targets of thieves. Visitors frequently fall prey to pickpockets, bag snatchers and other petty burglars. Theft from automobiles and hotel rooms is also on the rise. Never leave baggage or other valuables unattended. Within Amsterdam, thieves are very active in and around train and tram stations, the city center and on public transport.
