Serious offenses and offenders with more previous arrests were treated more harshly by the system. Slightly fewer than half the offenders arrested for index offenses were convicted, and just over half of those convicted were incarcerated. The likelihood of the conviction and incarceration of arrestees with serious criminal records was much greater than the conviction and incarceration of offenders with less serious records. Race affected certain dispositions. Early in the adjudication process and also at sentencing, nonwhites fared worse than whites. They were more likely to be held for court action and to be incarcerated after arrest. Racial discrimination was more likely to operate at points in the system where visibility and formal rules were less influential. Some evidence indicates that age or juvenile/adult criminal justice system differences influenced conviction and incarceration probabilities. 3 tables. (Author summary modified)
