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.
Sexual slavery
The Fundamentalist Church of Jesus Christ of Latter-Day Saints (FLDS) has been suspected of trafficking underage women across state lines, as well as across the US–Canada and US–Mexico borders, for the purpose of sometimes involuntary plural marriage and sexual abuse. The FLDS is suspected by the Royal Canadian Mounted Police of having trafficked more than 30 under-age girls from Canada to the United States between the late 1990s and 2006 to be entered into polygamous marriages. RCMP spokesman Dan Moskaluk said of the FLDS's activities: "In essence, it's human trafficking in connection with illicit sexual activity." According to the "Vancouver Sun," it's unclear whether or not Canada's anti-human trafficking statute can be effectively applied against the FLDS's pre-2005 activities, because the statute may not be able to be applied retroactively. An earlier three-year-long investigation by local authorities in British Columbia into allegations of sexual abuse, human trafficking, and forced marriages by the FLDS resulted in no charges, but did result in legislative change. Former FLDS members have also alleged that children belonging to the sect were forced to perform sexual acts as children upon older men while being unable to leave. This has been described by numerous former members as sexual slavery, and was reported as such by the "Sydney Morning Herald", One former resident of Yearning for Zion, Kathleen Mackert, stated: "I was required to perform oral sex on my father when I was seven, and it escalated from there."
