Pros
One reason mandatory sentencing guidelines are established is to increase sentencing uniformity -- to guarantee that defendants, who commit similar crimes and have similar criminal backgrounds, receive similar sentences. Mandatory guidelines for sentencing greatly curtail judges' sentencing discretion.
Without such mandatory sentencing, defendants in the past, guilty of virtually the same offenses under the same circumstances, have received vastly different sentences in the same jurisdiction, and in some cases from the same judge. Proponents argue that a lack of sentencing guidelines opens up the system to corruption.
Cons
A study performed by the Rand Company said such sentences have proven to be ineffective in curtailing drug use or drug related crime. "The bottom line is that only decision makers who are very myopic would find long sentences to be appealing," said study leader Jonathan Caulkins of Rand's Drug Policy Research Center. The high cost of incarceration and the small results that it has shown in fighting the war on drugs, show that such money would be better spent on shorter sentencing and drug rehabilitation programs.
Other opponents to mandatory sentencing include Court Justice Anthony Kennedy, who in August 2003 in a speech to the American Bar Association, denounced minimum mandatory prison terms. "In too many cases, mandatory minimum sentences are unwise and unjust," he said and encouraged the bar to be leaders in the search for justice in sentencing and in racial inequities.
Dennis W. Archer, former Detroit mayor and Michigan Supreme Court Justice takes the position that "it is time for America to stop getting tougher and start getting smarter against crime by reassessing mandatory sentencing and irrevocable prison terms." In an article posted on the ABA website, he states, "The idea that Congress can dictate a one-size-fits-all sentencing scheme does not make sense. Judges need to have the discretion to weigh the specifics of the cases before them and determine an appropriate sentence. There is a reason we give judges a gavel, not a rubber stamp"
Where it Stands
Research shows that drug court alternatives are not only more cost-effective than prison sentences for defendants who commit non-violent crimes, they help reduce the rate of defendants who return to a life of crime after completing the program.
