For anyone interested in Irish crime, I would highly recommend the Crimeworld podcast. They do mainly modern day organised crime, Kinahans, etc. but also talk about the history of crime in Ireland and occasionally have guests from abroad, psychologists, criminologists, and people from within the Irish legal/penal system. They give good insights into the whole system from the circumstances of crimes, background of the criminals, how the gardai work, the courts, sentencing, prison, etc. It can be surprising to hear how these experienced crime reporters view some elements of crime and punishment, including judges and sentencing.
