Police Get Confession with Undercover Cellmate and Fake Lineup VIOLATES Miranda Rights

California appeals court just REVERSED a murder conviction because police went too far with an undercover interrogation. In People v. Zapata (2026), the court ruled that once a suspect invokes their right to a lawyer, police can’t use undercover agents and coercive tactics to get around Miranda rights.

What happened: Jason Zapata was placed in a cell with undercover cops posing as inmates (a “Perkins operation”). After he asked for a lawyer, a deputy used a fake lineup and psychological pressure to trick him into confessing to murder. The confession got him convicted—but the Court of Appeal threw it out.

✅ Miranda v. Arizona – Your right to remain silent
✅ Edwards v. Arizona – Invoking your right to counsel
✅ Illinois v. Perkins – Undercover police operations
✅ Rhode Island v. Innis – What counts as “interrogation”
✅ When police tactics cross the constitutional line. This case creates a NEW LIMIT on Perkins operations: Known police officers can’t actively “stimulate” undercover interrogations after a suspect invokes Miranda rights.
