“They just snapped.”

It’s one of the easiest explanations we use after an act of extreme violence.

It’s also often wrong.

In Episode 3 of The Crime Doc Podcast, we examine what happens when warning behaviors are visible before violence occurs—and why recognizing them is far more complicated than hindsight makes it seem.

Using cases including Columbine and the behaviors surrounding Eric Harris and Dylan Klebold, we look beyond the simplified narratives that have developed after the fact.

What was actually known beforehand?

What only became significant after the violence occurred?

And how do we distinguish genuine behavioral warning signs from ordinary behavior that only looks suspicious in hindsight?

This isn’t about diagnosing people from a distance or pretending every tragedy could have been predicted.

It’s about understanding behavior, evidence, threat assessment, and the uncomfortable space between a warning sign and a predictable outcome.

Most of us believe we would never confess to a crime we didn’t commit. But false confessions happen—and the psychology behind them is far more complicated than it seems.

In Episode 2 of The Crime Doc, Dr. Sheard examines why innocent people sometimes confess, the difference between voluntary, compliant, and internalized false confessions, how interrogation conditions can affect decision-making, and why a confession can become such powerful evidence once we hear it.

The question isn’t simply, “Why would an innocent person confess?”

It’s:

What would have to happen before confessing started to feel like your best option?

Evidence over assumptions. Facts over narratives.

Can you diagnose a killer from a video—or are you seeing what you already believe?

In Episode 1 of The Crime Doc, Dr. Sheard examines criminal psychology, body language, deception analysis, hindsight bias, confirmation bias, and the dangers of diagnosing criminal behavior from short videos after the outcome is already known.

Can body language actually reveal guilt? Can facial expressions identify deception? And how much of what we think we see is influenced by already knowing what happened?

This episode explores the difference between observation and diagnosis, the limits of deception detection, and why legitimate psychological assessment requires far more than watching someone on a screen.

Nothing about the video changed. You did.

The Crime Doc examines true crime, criminal behavior, criminal justice, and forensic psychology through research and professional analysis—not sensationalism.
