About this episode

The episode discusses controversial undercover police stings in California jails and their implications on justice and racial bias.

Inside jails across California, a controversial police practice is happening. Undercover agents pose as incarcerated people. Their goal is to get confessions out of suspects. The tactics — known as Perkins Operations — have led to hundreds of murder convictions. But critics call the pratice coercion. They also say it promotes racially-biased policing. Now, the California Supreme Court is reviewing a number of convictions. On KPBS Midday Edition, we talk about a recent CalMatters investigation into Perkins Operations and the controversy surrounding them. Guest: Cayla Mihalovich , justice reporter and California Local News Fellow, CalMatters Cayla Mihalovich completed this story with the support of a grant from Columbia University’s Ira A. Lipman Center for Journalism and Civil and Human Rights in conjunction with Arnold Ventures.
