Six deranged members, plus another eleven implicated. Plus a blind eye turned by the rest of the people working there. Plus the fact that it's taken a year for this to come to public attention. I'd imagine that the rot sets deeper than you'd like to imagine. I'm not saying it's endemic, but I'd be willing to bet that it's not an isolated incident.
And I find it highly amusing to hear that these soldiers are not living up to their heritage. Solving all conflicts with war, marginalization of other cultures, cowboy diplomacy, double standards, international bullying. THAT is American heritage for you.
