In Norway we long had two systems to determine guilt. One was a jury system. A careful examination of the performance of both systems over many years concluded that the jury system was the worst. All serious miscarriages of justice we have had happened in a jury system.
A key reason identified was that juries don’t have written statements giving the reasoning for their judgment.
The jury system ended several years ago and nobody miss it. A panel of judges professional and selected among citizens akin to jury duty determines guilt.
