One aspect of this trial that no one seems to mention is that one of the assailants attacking Kyle faked surrender. Perfidy is specifically prohibited under the 1977 Protocol I Additional to the Geneva Conventions of 12 August 1949, which states: Protocol I of the Geneva Convention Article 37. 1. It is prohibited to kill, injure or capture an adversary by resort to perfidy. Acts inviting the confidence of an adversary to lead him to believe that he is entitled to, or is obliged to accord, protection under the rules of international law applicable in armed conflict, with intent to betray that confidence, shall constitute perfidy. Not that I suspect that piece of shit knew that at the time..
