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.
Trafficking of children
The Optional Protocol on the Sale of Children, Child Prostitution and Child Pornography is a protocol of the Convention on the Rights of the Child, formally adopted by the United Nations in 2000. Essentially, this protocol formally requires states to prohibit the sale of children, child prostitution, and child pornography. According to the International Labour Organization, sexual exploitation of children includes all of the following practices and activities: 
Though measuring the extent of this practice is difficult due to its criminal and covert nature, the International Labour Organization estimates that there are as many as 1.8 million children sexually trafficked worldwide, while UNICEF's 2006 State of the World's Children Report reports this number to be 2 million. The International Labour Organization has found that girls involved in other forms of child labour - such as domestic service or street vending - are at the highest risk of being pulled into commercial child sex trafficking. Likewise, Kendall and Funk justifies how “young girls age 12 and under are malleable and more easily trained into their prospective roles as prostitutes, and because virginity is highly prized by certain consumers willing to pay a premium” (31).A variety of sources, including the I.L.O, and scholars Erin Kunze and D.M. Hughes, also contend that the increased use and availability of the Internet has served as a major resource for traffickers, ultimately increasing the incidence of child sex trafficking. In fact, in 2009, Illinois Sheriff Thomas J. Dart sued the owners of Craigslist, a popular online classifieds website, for its "allowance" and "facilitation" of prostitution, particularly in children. In response to public and legal pressure, Craigslist has since blocked all access to its "Adult Services" section.
