Whatever view one holds about the penal law, no one will question its importance in society. This is the law on which men place their ultimate reliance for protection against all the deepest injuries that human conduct can inflict on individuals and institutions. By the same token, penal law governs the strongest force we permit official agencies to bring to bear on individuals. Its promise as an instrument of safety is matched only by its power to destroy. If penal law is weak or ineffective, basic human interests are in jeopardy. If it is harsh or arbitrary in its impact, it works gross injustice on those caught within its coils. The law that carries such responsibilities should surely be as rational and just as law can be. Nowhere in the entire legal field is more at stake for the community, for the individual.
