Prostitution law
However, sex worker activists and organizations distinguish between human trafficking and legitimate sex work, and assert the importance of recognizing that trafficking is not synonymous with sex work. The Sex Workers Alliance Ireland organization explains: "victims of human trafficking may be forced to work in industries such as agriculture, domestic service as well as the sex industry. It is critical to distinguish human trafficking, which is a violation of human rights, from voluntary migration." The Open Society Foundations organization states: "sex work is done by consenting adults, where the act of selling or buying sexual services is not a violation of human rights. In fact, sex workers are natural allies in the fight against trafficking. The UNAIDS Guidance Note on HIV and Sex Work recognizes that sex worker organizations are best positioned to refer people who are victims of trafficking to appropriate services."
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."
