Episode 02 - Perugia: When Four Systems Fail Together
What happens when a media narrative, cognitive bias, a legal structure, and a single prosecutor all fail in the same direction at the same time? In this episode, forensic psychologist Melissa Deadrich breaks down the Meredith Kercher case — not as a celebrity true crime story, but as a case study in how systems collapse together and real people absorb the damage.
Topics covered:
- How a nickname became one of the most powerful framing devices in modern true crime
- Attribution error and confirmation bias inside a legal system
- The structural differences between the Italian and American legal systems
- The prosecutor's documented history before this case ever began
- The lasting ripple effects on Patrick Lumumba, Rudy Guede, Amanda Knox, and the Kercher family
