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.
