It is the unfortunate consequence of an imperfect Justice system that the guilty will sometimes go free and occasionally the innocent will be punished. The philosophy behind proving guilt “beyond a reasonable doubt” is that the latter will occur much less frequently. Sadly, it occurs more often than a free society should be comfortable with as the ever-increasing number of exonerations through DNA testing makes clear.
In 1982, Kenneth Waters of Ayer, Massachusetts, was tried and convicted for the brutal murder of a neighbor. He was sentenced to life imprisonment. His sister, Betty-Anne, always believed in his innocence and so she got her GED, a BA and then finally a law degree so she could personally take on the cause of getting her older brother out of prison. In the end, DNA evidence overturned his conviction and set him free.
