The most common menace, especially in large cities (particularly Rome), is the plague of pickpockets and roving gangs of gipsy children who virtually surround you, distract you, and in the confusion try to steal your purse or wallet. Never leave valuables in a car, and never travel with your car unlocked. In these uncertain times, it is always prudent to check the U.S. State Department's travel advisories at http://travel.state.gov/travel/warnings.html.(Source: frommers.com)
