WASHINGTON, DC--Representatives Rosa DeLauro (D-CT), Carolyn Maloney (D-NY) and Randy Weber (R-TX) led 36 members of Congress in calling on Attorney General Eric Holder to address the demand side of sex trafficking. Like drugs and arms trafficking, human trafficking is a market-driven criminal industry that is based on the principles of supply and demand. Historically, the brunt of social and official stigma has fallen squarely on the supply side allowing the social stigma to fall on the victims. Law enforcement is only starting to realize that the best way to reduce prostitution is to crack down on the demand.
