William Douglas Morrison, Crime and Its Causes
“ Were it possible for the hand of social justice to descend on every criminal with infallible certainty; were it universally true that no crime could possibly escape punishment, that every offence against society would inevitably and immediately be visited on the offender, the tendency to commit crime would probably become as rare as the tendency of an ordinary human being to thrust his hand into the fire. The uncertainty of punishment is the great bulwark of crime, and crime has a marvellous knack of diminishing in proportion as this uncertainty decreases. ”
