Human trafficking and human smuggling are different crimes. Some people can get trapped in slavery without crossing a border. . .
US federal law in 2000, gave this definition of trafficking: “the recruitment, harboring, transportation, provision, or obtaining of a person for labor or services, through the use of force, fraud, or coercion for the purpose of subjection to involuntary servitude, peonage, debt bondage, or slavery.” Take note that this definition applies also to sex trafficking and forced labor. Coercion and force and fraud all can play major roles in trapping victims.
