Although it is a widespread practice in the United States to increase criminal penalties for people with prior convictions, there is little evidence that this practice advances public safety.1 Research by the Robina Institute has shown that state and federal sentencing guidelines dramatically increase sentence lengths based on individuals’ prior criminal records. This effect is even more pronounced for African Americans. Given the limited public safety benefits from criminal record “enhancements” and the accompanying harms to incarcerated individuals, their families, and communities — and the steep financial costs — this further lengthening of sentences should be reconfigured.
