I understand and share your discontent with the deviations from acceptable and lawful practice within the American justice system, particularly with regard to the "detainees."  However to compare or contrast these deviations, horrible as they appear today in western society, with the situation that prevailed during medieval times stretches the point beyond exaggeration.  If you insist on pursuing this line of thought, I suggest engaging in far more research into what was widely practiced as "justice" during human history prior to say, the 19th century.
