Difference between Human Trafficking and Smuggling:
Though they are often confused, human trafficking and smuggling are separate and fundamentally different crimes. Human trafficking is a crime against the person whereas smuggling is a crime against the state. Smuggling occurs when a person voluntarily requests or hires a person, known as a smuggler, to transport him or her across a border for a fee.
At least theoretically, a person who is smuggled into the United States is free to leave upon payment of a prearranged fee, while a victim of human trafficking is enslaved to supply labor or services. Unlike smuggling, the crime of human trafficking does not require travel or transportation of the victim across borders. Thus, human trafficking can (and does) occur domestically, with victims who are born and raised in California and other states.
