There are 18,000+ active court martial proceedings underway at any given time in the US services. Our 1,000,000+ US troops commit offenses, from wife beating to theft to murder, and always have. The press needs to look at everything in perspective. Our military personnel are mostly made up of fine young men and women. But many factors, let alone the circumstances of serving in a hotile combat environment, make some folks, including US G.I.'s go bad. In Vietnam we had fraggings (murder of superiors), drug dealing, rampant theft, etc on an ongoing basis. The military teaches you that it's ok to kill. So a lot of troops say to themselves, "During my tour, anything goes." Unfortunately, they often live, at least at times, with that code, for the rest of their lives.
And I have no doubt that they do.
They just don't report it in that same fashion! ; )
