Mandatory sentencing increases consistency in the justice system.  Former Supreme Justice Sandra Day O’Connor once said, “liberty finds no refuge in a jurisprudence of doubt.” [1] Without mandates, judges may have radically different ideas of just sentences. Michael Simons gives the example of Mutt and Jim- two criminals of identical background who commit the same crime. Judge Lenient sentences Mutt, while Judge Harsh sentences Jeff. Mutt might receive one day in prison while Jeff receives a sentence of twenty-five years. [2] While such an extreme is unlikely, it is noteworthy that the legal system emphasizes the importance of consistency. Consistent precedent is essential because citizens need to be able to make decisions knowing the legal consequences of their actions. Mandatory sentencing need not be overly harsh, but there should be some sort of rigidity to establish reliability in the legal system.  [1] Planned Parenthood v. Casey, 505 U.S. 83, (1992).
