Statutory relief results in significantly reduced sentences when applied
" More than half (51.6%) of offenders convicted of an offense carrying a drug mandatory minimum penalty received relief at sentencing.
" In fiscal year 2016, 21.8 percent of offenders convicted of a drug mandatory minimum penalty qualified for relief under the safety valve, 21.5 percent received relief for providing substantial assistance, and 8.2 percent received relief for both safety valve and substantial assistance.
" Offenders who received safety valve relief (57 months) or provided substantial assistance (81 months) received significantly lower sentences than those offenders who remained subject to a drug mandatory minimum penalty at sentencing (126 months). Offenders who received both safety valve relief and provided substantial assistance had even lower average sentences (41 months)."
