Central to determinate sentencing is the idea that punishment should fit the crime and consider criminal history to be fair. Requiring harsher sentences for serious crimes addresses public safety, but mandatory additions to sentences for repeat offenses are often seen as unjust, such as a man receiving 25 years to life for petty thefts of $150. Long sentences for low-level crimes also crowd prisons and strain economic resources. There must be a balance between consistent sentencing and addressing the financial burden of mass incarceration.
