Why Punish?

This chapter examines the most basic question:  Why punish all at? 

Throughout this course, I hope that you keep in mind that criminal laws are supposed to serve an end.  There should an important need to enforce a rule with a criminal sanction.  Criminal laws are not an end unto themselves - it is not enough to justify punishment in the form of imprisonment or other loss of liberty or property to simply say "he/she/they broke a rule." 

This chapter should help you begin to work through the process of determining when and why punishment is necessary or good.
