Bradley #Manning's Legal Duty to Expose #WarCrimes — http://www.truth-out.org/news/item/16731-bradley-mannings-legal-duty-to-expose-war-crimes
Manning fulfilled his legal duty to report war crimes. He complied with his legal duty to obey lawful orders but also his legal duty to disobey unlawful orders.
Section 499 of the Army Field Manual states, “Every violation of the law of war is a war crime.” The law of war is contained in the Geneva Conventions.
Article 85 of the First Protocol to the Geneva Conventions describes making the civilian population or individual civilians the object of attack as a grave breach. The firing on and killing of civilians shown in the “Collateral Murder - Wikileaks - Iraq" video violated this provision of Geneva.
