I think it'd be a better idea to discuss only the US system, to be honest. Otherwise this might become a bit disorganized. That, and if I brought up the Norwegian justice system, the thread would easily get cluttered by "WTF?!" posts, Danish Animal Bordellos-thread-style
As for the US system:
Do you think the American system of justice is too harsh, too forgiving, or just right ?
It depends on scenario. Too mild in some cases, too harsh in others.
One gripe I've got it how it treats minor offenders. Remember this thread here on LucasForums about how this elderly man was handcuffed to a coloumn in a general store for paying with a $2-bill (the staff thought it was counterfeit as they were ignorant enough not to know of two-dollar bills).
Hello? Handcuffing some elderly citizen for passing a "counterfeit" bill?
Or this story about the two high school kids who sneaked into campus grounds at night to play ball, and wound up in the arrest for trespassing.
I could also bring up tonnes of stories about little children being handcuffed for nothing (this 12-year old who brought scissors to school comes to mind).
One thing to discuss.
There's also the fact that the rich, with their powerful lawyers, have a much easier time in the face of the law than, say, a poverty-stricken Latin-American family. Rape a high-class white girl and a low-class Latin girl and see which you have to stand trial for first.
