The trial podium, which deals with known cases, uses the principle of publicity to solicit audio recordings from, among others, trials, police hearings and alarm calls to 112. The material is then clipped to radio documentaries where listeners hear relatives and perpetrators' other stories about murders.

The cultural news review shows that five families whose cases have been raised in the Trial have not been asked if they wanted to participate in the pod before the sections were published. They describe it as "a blow to the face" and that it has led to a "recurrence of the trauma".

"We have our routines"

The creator of the trial, Nils Bergman, has also made two documentary series for SVT. One of them is about the so-called Arboga case. Jewish recordings are also used in the series. However, Ingemar Persson believes that all relatives heard in the Arboga Falls have been contacted before the series was broadcast.

"After all, we have our routines and everyone involved is contacted in advance and given their approval," he says.

"Would have acted differently if we knew"

Ingemar Persson, at the interview, did not take part in the entire investigation and has not previously heard that criticism was directed at Nils Bergman and the trial court.

- If we had known that there was such dissatisfaction, we probably would have thought about it. Obviously we would have acted differently if we knew from the start, says Ingemar Persson.
