In 1993, in West Memphis Arkansas, three children were murdered and three teenagers were convicted of these murders. The plight of these convicts was documented in the 1996 film Paradise Lost, which made the case that these teenagers had been wrongly convicted due to local prejudice against their counter-cultural attitudes. Additional evidence has been revealed that casts further doubt upon their guilt.
Assuming these boys (men now) were wrongly convicted, they have suffered a great wrong. However, when I think of "Paradise Lost", I don't think of their personal suffering -- I think of the tragedy that our society (and probably any society) exhibits such bias in the implementation of justice. The movement supporting these men is based on the perception that they were thrown in jail for being different, not because of anything illegal that they did; regardless of how fair the law is, the law still has to be implemented by humans.
I think that the American justice system includes some ingenious mechanisms to remove personal bias from decisions in criminal cases. I can also think of some ways to reduce the influence of personal bias, such as providing adequate counsel to the accused, and cutting back on the frivolous reasons for throwing people in jail (such as the drug war). However, in the end, it seems that fairness of the legal system is limited by the fairness of the people in the society.
