Modifies provisions relating to minimum prison terms

HB 2880 increases mandatory minimum prison terms for certain felony offenders in Missouri. It requires non-dangerous felony offenders with prior prison commitments to serve 80% of their sentence (up from 40-50% under current law), while those without prior commitments must serve 75% (up from 70%). Dangerous felons must serve 85% of their sentence. The bill also creates a Sentencing Advisory Commission to study sentencing disparities and alternative programs like probation and work release. It directly affects repeat felony offenders sentenced under the specified statutes.
