Yes. Brings to mind a disturbing movie that we watched recently; "The Whistleblower" -- based on the experiences of Kathryn Bolkovac, an American police officer who in 1999 was assigned to serve as a peacekeeper with the United Nations in post-war Bosnia. While there, she reportedly discovered a sex-trafficking ring which served and was facilitated by other peacekeepers.
Warning -- the movie is very graphic and disturbing --
