Rummy says that the most horrific tapes and photos haven't been seen by the public yet. Murder, raping of women and young boys, beating POW's to near death.
We like to think that only "the other guy" plays these shitty games, but our own people are just as bad. Some people wonder how on Earth other countries hate Americans?
Do you remember when you were 18-25? You thought you knew everything, and no one could tell you any different. Look around at the 18-25 year olds on campus, in the clubs, at work, etc. The maturity level isn't that high, in general. Now, give that kid a "mission", and a weapon, drop them in with a few thousand more, and it doesn't take long for some of them to faction off into their own little niche, and become complete assholes.
Ultimately, the top brass is responsible, but to think they know everything happening in the field is ridiculous.
