As much as we would like to think that our justice system is airtight, effective, and above all, just, there have always been circumstances in which those who commit atrocities get off scot-free and those who are merely defending themselves are forced to endure life-ruining punishment.
Laws are incredibly important, but they don't always allow for understanding in extreme or rare circumstances, which begs a difficult to answer question: Is "justice" having someone suffer the proper punishment for the legal crime committed, or does it involve a level of case-by-case empathy?
