These vulnerabilities are the result of policies and practices that marginalize entire groups of people and make them particularly susceptible to exploitation. Traffickers use these vulnerabilities to their advantage and use a number of tactics to establish control over victims. Violence, isolation, threats, deception, manipulation, debt bondage, prospects of education, and romance are just a few methods used. Traffickers may operate alone with one or many victims or maybe a part of an extensive criminal network. Examples of trafficking rings include gang members, family members, pimps, business owners, or smugglers.
