Answer :
E) Mandatory minimum sentences are needed (NECESSARY) to help prevent judicial arbitrariness is most accurately expresses the main point of the passage.
These statutes are seen as mechanical and rigid, seemingly limiting a judge's discretion in identifying whether an individual can be rehabilitated. However, the main point of the passage is that mandatory minimum sentences are necessary to prevent judicial arbitrariness.
History shows that when people use their own judgment, they can be irrational and arbitrary, and judges are no exception.
In the 1970s, parole and time off for good behavior were common, which provided incentives for good conduct and skill acquisition in prisons.
However, media reports on crimes committed by parolees led to "truth-in-sentencing" laws, establishing mandatory minimums or fixed sentences to reduce crimes committed by previously paroled individuals.
This change aimed to make the justice system more stringent and reduce subjective decisions from judges that could lead to inconsistent justice outcomes.
