On June 2, 2000, members of the 48th Military Police Detachment conducted a sting on the DynCorp hangar at Comanche Base Camp, one of two U.S. bases in Bosnia, and all DynCorp personnel were detained for questioning. CID spent several weeks working the investigation and the results appear to support Johnston's allegations. For example, according to DynCorp employee Kevin Werner's sworn statement to CID, "during my last six months I have come to know a man we call 'Debeli,' which is Bosnian for fat boy. He is the operator of a nightclub by the name of Harley's that offers prostitution. Women are sold hourly, nightly or permanently."[19]
Johnston is not the only DynCorp employee to blow the whistle and sue the billion-dollar government contractor. Kathryn Bolkovac, a U.N. International Police Force monitor hired by the U.S. company on another U.N.-related contract, filed a lawsuit in Great Britain against DynCorp for unfair dismissal due to a protected disclosure (whistleblowing), and on 2 August 2002 the tribunal unanimously found in her favor.[20] DynCorp had a $15 million contract to hire and train police officers for duty in Bosnia at the time she reported such officers were paying for prostitutes and participating in sex-trafficking.[21] Many of these were forced to resign under suspicion of illegal activity, but none have been prosecuted, as they also enjoy immunity from prosecution in Bosnia. Bolkovac's story was made into a film, The Whistleblower, in 2010. She has also co-authored a 2011 book with Cari Lynn titled The Whistleblower: Sex Trafficking, Military Contractors And One Woman's Fight For Justice.
DynCorp has admitted it fired five employees for similar illegal activities prior to Johnston's charges.[22] In the summer of 2005, the United States Defense department drafted a proposal to prohibit defense contractor involvement in human trafficking for forced prostitution and labor. Several defense contractors, among others DynCorp, stalled the establishment of a final proposal that would formally prohibit defense contractor involvement in these activities.[23]
