Blackcatter, you seem to be belittling the difference between the legal system which pays heed to a code of laws and due process, and one which is arbitrary and based on religion as defined at the time by the judge on the spot. Take note that plea agreements occur when there IS evidence, the accused can take it to trial if they feel they will win, if the DA had all the cards, they could imprison anybody for any time and not have to plead at all.

The system is FAR from perfect, but Dickens had it a lot more accurately than you do. In the West, the Law is an Ass, in countries like the one mentioned here, Lewis Carroll had it right: "I'll be Judge, I'll be Jury, said cunning old Fury, I'll hear the whole thing and sentence you to death!" (more or less)
