[The Global Policy Forum] [a] non-profit organization that monitors the United Nations published a report...criticizing the UN's growing use of private military and security companies...The Global Policy Forum said the UN's increasing use of these companies is "dangerous," may increase rather than reduce threats and attacks on U.N. buildings and personnel, and suggests a system that is "unaccountable and out of control."...UN spokesman Martin Nesirky said the United Nations believes it is appropriate to use armed private security contractors if the organization ensures "due diligence" in its operations...According to the report, "in the absence of guidelines and clear responsibility for security outsourcing, the UN has hired companies well-known for their misconduct, violence and financial irregularities — and hired them repeatedly."
