Officer perjury triggers mass dismissals

When a police witness is exposed as a serial perjurer, prosecutors often must abandon dozens of unrelated cases that hinge on that officer’s testimony. In Chicago, at least 92 traffic and criminal matters were dropped after a veteran cop admitted lying under oath to beat 56 of his own tickets. This illustrates the Giglio/Brady domino effect and the high cost of weak misconduct controls. — It spotlights a systemic vulnerability—officer credibility management—where one bad actor can undermine courts, prosecutions, and trust, informing reforms on disclosure lists, decertification, and complaint procedures.
