You would not either, until you personally had to pick up the pieces of a friend, who you'd shared hardships, hopes and beers with, basically a part of your life, and put them quickly into a plastic bag. You get no time to reflect, or grieve, or you might find yourself in a bag next to them. I'm not saying these lads are innocent...(only a court of law can say they are guilty, and they do deserve a day in court, don't they? Or is that only for folks like OJ, Baretta, and Ken Lay?)
Some of the other countries do sweep this under the rug; but thankfully, ours is a reflective nation, and some of our people do have the moral courage to stand up for what is right and question things. How do you think we got the information in the first place? A Marine, with moral courage, did bring this to someone's attention. You should be applauding that Marine, who did witness the carnage personally, who was able to hold on to his sense of humanity, and still had the guts to go against superior NCO's and Officers, and report his findings.
I find it ironic you bring up Hitler ....99.9% of the population in Iraq (or Iran, or Syria, or damn near anywhere else in the ME except for Israel....)would tell you that Hitler didn't do enough. And I'll bet you didn't even think about the idea that the Iraqi's (Sunni and Shiite) are commiting more atrocities against their fellow citizens, that the entire coalition has.
