War Crime

It all depends on who writes the history books:

Under international agreements, people who are not part of a country's military can carry weapons and defend themselves. But some are wondering whether the legal status of security contractors is compromised because of the increasing number of reports that these private guards are actually involved in a significant amount of offensive operations. Besides bringing international scrutiny, this could turn out to be particularly embarrassing for the administration because it has said that those being held in Guantanamo are unlawful combatants since they aren't part of a nation's military. "If we hire people and direct them to perform activities that are direct participation in hostilities, then at least by the Guantanamo standard, that is a war crime," an expert said.
