I recently watched After Innocence, which is a documentary that sums up many of the reasons why I despise the American legal system.
It is a documentary about innocent people who were placed into American prisons (often by people who knew they were innocent), and now have to carry the stigma around with them (a stigma that they do not deserve) for the rest of their lives even after they were released. In fact, sometimes people who actually do the crime are better off than these folks are, ironically enough.
I had no faith in American law before I watched this film - now I have even less. Heh.
