The Iraq "detainee/prisoner" abuse scandal at the United States detainee facilities have yet to be totally determined.
These type situations would not have mushroomed as they have were it not for the arbitrary and secret environment they are cast into.
In contrast, consider out criminal system where "suspects/prisoners" are given a Miranda warning, allowed a phone call, get legal representation and can have visitors. Here our rule of law system works because a humane system of transparency, respect and openness discourages dark and secret environments.
The United States can regain our moral high ground by prosecuting all the aiders and abettors of detainee abuse, adapt our rule of law system for all detainees, re-affiliate with the International Criminal Court treaty and more truly interact with other nations.
