Kathryn Bolkovac arrived in the Bosnian capital of Sarajevo in 1999. A former police officer from Lincoln, Nebraska, she was grateful to join the U.N.'s International Police Task Force (IPTF) that was retraining local law enforcement there. Bolkovac was to work alongside officers from dozens of countries under the umbrella of DynCorp, a defense contractor. But it didn't take long for Bolkovac to realize that DynCorp was engaging in the kinds of human rights violations it was meant to combat. While there, she made the harrowing discovery of a child sex trafficking ring that not only was connected to the company's most powerful people but was also being covered up by the United Nations. [Bolkovac] found that many international aid workers on her task force had not only engaged in prostitution and child rape, but facilitated these operations at secretive establishments across the city. Victims confided in her that American contractors were raping or buying underage women, sometimes as young as 12. There were no safe homes to place victims in. Many were either simply jailed or deported, at which point law enforcement on the other side forced them back into prostitution. Bolkovovac ... was blocked every time she tried to bring her concerns to someone above her in DynCorp. Finally, after a series of ineffective raids at various establishments, Bolkovac decided to officially blow the whistle [and] was demoted to a desk job.
