Explain what Twelve Angry Men has to say about justice for the individual.

Rose's work argues that the most basic benchmark of our
system of justice is ensuring a sense of fairness within the law for the individual. 
Justice is defined as an ability to ensure that all individuals are presumed innocent
until proven guilty.  In the end, the play shows and highlights this theme.  While some
of the jurors are either unfit for service, or prove to have their own subjective
experience blind them from such a reality, the play does show that all jurors have to
work together to ensure that the due process of the individual is fully grasped and
understood.  In this light, justice is something that has to be pursued, as individual
temperament and disposition might subvert it.  Justice cannot be something that is
openly and easily accepted, or taken for granted.  Instead, it is something to be
embraced carefully and done so with a disposition that protects the idea that the
individual is entitled to fairness within the law.
