Argentina is considered to be one of south America's safest countries, still, in the big cities there is good reason to take care. In Buenos Aires and other popular tourist destinations be on guard for scam artists and purse-snatchers on the street and at bus and train stations, as well as in cruise ship ports. Criminals usually work in groups and are often armed. Criminals employ a variety of ruses to distract and victimize unsuspecting visitors. Argentina's legal system is similar to those of Europe and north America, or rather it takes elements from both mixing Civil and Common Law.
