One night in jail: So concludes the Duke lacrosse rape case — rape fraud, as it turned out. The legacy of this incident should include hard thinking about the deep pathologies underlying the media sensationalism and the perversion of academic ideals that this fraud inspired.

The 24-hour sentence was imposed on Mike Nifong, the disbarred former district attorney of Durham, after a contempt-of-court trial last week for repeatedly lying to hide DNA evidence of innocence. His prosecution of three demonstrably innocent defendants, based on an emotionally disturbed stripper’s ever-changing account, may be the worst prosecutorial misconduct ever exposed while it was happening. Durham police officers and other officials aided Nifong, and the city and county face the threat of a massive lawsuit by the falsely accused former students seeking criminal justice reforms and compensation.

All this shows how the criminal justice process can oppress the innocent — usually poor people lacking the resources to fight back — and illustrates the need for reforms to restrain rogue prosecutors. But the case was also a major cultural event exposing habits of mind among academics and journalists that contradict what should be their lodestar: the pursuit of truth.

Nifong’s lies, his inflaming of racial hatred (to win the black vote in his election campaign) and his targeting of innocent people were hardly representative of criminal prosecutors. But the smearing of the lacrosse players as racist, sexist, thuggish louts by many was all too representative.
