Conflict theory and previous research suggest that the Black-White difference in support for harsh criminal punishments may be linked to anti-Black prejudice among Whites and perceived injustice among Blacks. Using survey data from the 2001 Race, Crime and Public Opinion Study, this article examines the sources of the racial gap in levels of punitiveness. Two main explanations are tested: perceived racial bias in the criminal justice system and racial prejudice. The results indicate that, together, racial prejudice and perceived racial bias explain the Black-White gap in punitive attitudes. (C) 2008 Elsevier Ltd. All rights reserved.
