“We lead U.S. global engagement to combat human trafficking and support the coordination of anti-trafficking efforts across the U.S. government. The United States follows the widely used “3P” paradigm — prosecution, protection, and prevention — to combat human trafficking worldwide. We also employ a “4th P” — for partnership — as a complementary means to achieve progress across the 3Ps and enlist all segments of society in the fight against modern slavery.”

The benefactor:
Sometimes people know that you are homeless. If you are young, and perhaps very pretty or have some kind of odd feature that is attractive, a more affluent potential protector may make it known that he wants to save you. (Again, sometimes a protector may be a she, but a he is more common). He may have a wife and even a daughter your very own age. He has all the best intentions for you – clean clothes, a warm bed, a shower, food. He might even take you shopping and out to a fancy restaurant . . .
