Fernando Guzzi was known as a good confession obtainer. So his director asked him to join the police academy and teach other officers how to do the same.

To prepare, Fernando started reading the research. And what he found made him want to go back through every case he had ever closed.

🎧 In Episode 24 of Davidhorn podcast Beyond a Reasonable Doubt, this Police Commissioner from Santa Catarina, Brazil, talks to Dr. Ivar Fahsing about the moment he realised he had not been gathering information - he had been confirming his own hypotheses. And about what it takes to change that, not just in yourself, but inside an institution still shaped by the legacy of military dictatorship.

‼️ One of the most striking lines in the conversation: Fernando describes being able to make almost anyone say almost anything - and why that is precisely the reason investigative interviewing matters.

Dr. Adrian J Gates led investigative interview training at the Garda College in Ireland. His doctoral research has now produced a number that is hard to ignore.

When a suspect interview is recorded on video and simultaneously written down by hand — as Irish law requires — the written statement captures 39% of what was actually said. Across 15 interviews, that meant 4,481 omitted items. And the problem is not just what gets left out. The act of writing actively interrupts the interview itself, stopping people mid-flow so the pen can catch up.

In Episode 23 of Davidhorn's podcast Beyond a Reasonable Doubt, Dr. Gates talks to Dr. Ivar Fahsing about what that means for justice — and about his own journey from confession-focused detective to the person who stood up in front of the assistant commissioner and said yes, we have been doing it wrong.

In March 2022, while part of Kyiv was still under occupation, Vasylyna Yavorska received a call from the Office of the Prosecutor General: could her team develop guidelines for interviewing prisoners of war?

That moment sits at the heart of this episode of Beyond a Reasonable Doubt — recorded live at the Davidhorn Police Interview Summit in Manchester and hosted by Dr. Ivar Fahsing.

Vasylyna is a Ukrainian lawyer and CEO of JustGroup, and she has led the country's national expert team on investigative interviewing since 2017. She talks about what it takes to shift a criminal justice system away from confession-based thinking, how you build change from the inside out, and why Ukraine's war crimes investigators — having now conducted over 2,000 interviews — may soon be teaching the rest of us.

One exchange that stayed with us: in 2020, 61% of Ukrainian investigators defined a confession as the measure of a successful interview. What Vasylyna is working to replace that with is not just a methodology. It is a different set of values.

What does it actually take to prevent torture in Europe?

Not just better interview methods. Better systems, better culture, and independent oversight that arrives unannounced — at midnight on a Friday, when the cells are fullest.

In Episode 21 of Davidhorn podcast Beyond a Reasonable Doubt, Dr. Ivar Fahsing speaks with Therese Maria Rytter - international human rights lawyer, outgoing Vice-President of the European Committee for the Prevention of Torture (CPT), and co-author of the Méndez Principles. For nearly 12 years, she led delegations into police stations, prisons, and psychiatric facilities across 46 countries: speaking with detainees, examining injuries, reviewing use-of-force records.

The conversation is both candid and uncomfortable.

Why do some countries still reward officers for high confession rates?

Why is Denmark - a global leader on torture prevention - still not recording suspect interviews?

And what does it mean for an investigator to truly uphold a suspect's rights, rather than talk them out of exercising those rights?

One point lands clearly: investigative interviewing cannot be viewed in isolation. The safeguards, the culture, the judiciary, the political will — it all has to move together.

Months or years later, that conversation may be reviewed during an appeal or legal process. At that point, the interview recording often becomes central to the case.

Immigration and asylum interviews are complex and sensitive, often involving interpreters, multiple languages and details that later come under scrutiny.

Questions arise:
▪ Was the interview captured clearly?
▪ Was it stored securely?
▪ Can the evidence withstand legal review?

In our latest Davidhorn Blog article, we explore:
✓ Why interview recording matters in asylum procedures
✓ Key EU requirements around immigration interview recording
✓ Common operational challenges authorities face
✓ How technology can improve integrity and reduce post-interview work

Why do officers interview the way they do - even when they know better?

In the latest episode of our podcast Beyond a Reasonable Doubt, Dr. Ivar Fahsing speaks with Ahmet Demirden, Ph.D. - former Toronto police officer, psychologist, and international training specialist - about the gap between knowledge and practice in investigative interviewing.

Regulatory focus, organisational culture, required drivers, and the promise of AI feedback tools.

Something special is happening at the Davidhorn Police Interview Summit 2026.

On the evening of 22 April, we will be recording a live episode of Beyond a Reasonable Doubt podcast — right there in the room, with our delegates as the audience.

Our guest is Vasylyna Yavorska from JustGroup, Ukraine — whose work supporting Ukrainian investigators and prosecutors under extraordinarily difficult conditions speaks directly to this year's theme: Understanding. Conversation will be hosted by Dr. Ivar Fahsing.

What does it mean to build fair, evidence-based interview practice during active conflict? What does justice look like when the pressure is immense and the stakes could not be higher?

We cannot think of a more important conversation to have — or a better place to have it.

Registration for Davidhorn Police Interview Summit 2026 is now closed, we will announce the next year's date soon. Watch this space!

Finland has some of the strongest child interview practices in Europe.
It also has police officers who, when surveyed, knew almost nothing about investigative interviewing methods for adults.

That gap — between what exists and what is actually implemented — is exactly what Episode 19 of our podcast Beyond a Reasonable Doubt is about.

Dr. Ivar Fahsing speaks with Julia Korkman, one of the Nordic region's leading legal psychologists, about what it really takes to shift a system.

Honest, specific, and grounded in decades of practice.
