"The United States' commitment to fighting modern slavery did not simply materialize 12 years ago with the passage of the Trafficking Victims Protection Act or the adoption the same year of the U.N. Protocol to Prevent, Suppress and Punish Trafficking in Persons, Especially Women and Children (Palermo Protocol). This country's tragic history is not forgotten, nor are the bloodshed and lives lost in the fight to end state-sanctioned slavery. The year 2012 will mark the 150th anniversary of the date Abraham Lincoln gave notice of the Emancipation Proclamation. That document and the 13th Amendment to the United States Constitution, following three years later, represent more than policies written on paper. They represent the promise of freedom. […] Human trafficking appears in many guises. It might take the form of compelled commercial sexual exploitation, the prostitution of minors, debt bondage, or forced labor. The United States government, and increasingly, the international community, view 'trafficking in persons' as the term through which all forms of modern slavery are criminalized. Why, then, are so many different actions considered the same crime? Why are so many terms used to describe one human rights abuse? Exploitation lies at the core of modern slavery. Whether held on a worksite or trapped in prostitution, a victim of this crime has suffered an infringement of the right to be free from enslavement."
