There are about 6000 archaeological sites in Italy. And artifacts are stolen every day. Combatting the ever-growing trade in stolen art is a special squad of Italian police. “In more than 30 years of activity, the squad has retrieved about 185,000 works of art and 456,000 archaeological objects. The original force of a few dozen police officers has grown to 300, with branches throughout Italy and liaisons throughout the world. Its database of stolen art, called Leonardo, catalogs more than two million objects.”
