The word "trafficking" seems ill-defined to me. Between ordinary transportation (I travel to Italy to take a job I'm excited about) and coerced transportation into a condition of plain enslavement sits a very big spectrum. Are "coyotes" at the Mexican border "traffickers", if they are hired voluntarily (by people in great distress, for sure) and work to deliver the (illegal) service they have sold? What exactly renders transportation "trafficking"?
