Human trafficking
The problems against anti-trafficking raids are related to the problem of the trafficking concept itself, as raids' purpose of fighting sex trafficking may be conflated with fighting prostitution. The Trafficking Victims Protection Re-authorization Act of 2005 (TVPRA) gives state and local law enforcement funding to prosecute customers of commercial sex, therefore some law enforcement agencies make no distinction between prostitution and sex trafficking. One study interviewed women who have experienced law enforcement operations as sex workers and found that during these raids meant to combat human trafficking, none of the women were ever identified as trafficking victims, and only one woman was asked whether she was coerced into sex work. The conflation of trafficking with prostitution, then, does not serve to adequately identify trafficking and help the victims. Raids are also problematic in that the women involved were most likely unclear about who was conducting the raid, what the purpose of the raid was, and what the outcomes of the raid would be.
Slavery
While the majority of trafficking victims are women, and sometimes children, who are forced into prostitution (in which case the practice is called sex trafficking), victims also include men, women and children who are forced into manual labour. Due to the illegal nature of human trafficking, its exact extent is unknown. A U.S. government report, published in 2005, estimates that about 700,000 people worldwide are trafficked across borders each year. This figure does not include those who are trafficked internally. Another research effort revealed that roughly 1.5 million individuals are trafficked either internally or internationally each year, of which about 500,000 are sex trafficking victims.
