Ceisteanna ó Cheannairí - Leaders' Questions Dail Éireann — 2026-09-16 ============================================================ Mary Lou McDonald (SF), Dublin Central RTÉ has reported very serious allegations and tonight four Garda whistleblowers will speak publicly on them for the very first time. They will detail how the process for reporting and investigating wrongdoing within the Garda has been repeatedly undermined by senior management, including former Garda Commissioner, Drew Harris. A process was established in the aftermath of scandals that rocked An Garda Síochána more than a decade ago, in particular the treatment of sergeant Maurice McCabe. At that time, we were promised a fresh start. However, the Garda whistleblowers on tonight's programme say that instead of being protected, whistleblowers are targeted, penalised and vilified by those at the very top for making disclosures of wrongdoing. Protected disclosures made by these whistleblowers include the dangerous storage, movement and handling of firearms, defective ammunition and the issuing of defective holsters - all of which put gardaí at risk. Those speaking out are senior members of An Garda Síochána. They include Dr. Donal Corcoran, the person who was in charge of the Garda protected disclosures office; Ms Rose Sweeney, a case manager; and Detective Superintendent Brian O’Reilly, head of the Garda Technical Bureau. What is absolutely astonishing here is that the very person running the protected disclosures office, Dr. Corcoran, and another charged with managing protected disclosures cases, Ms Sweeney, were themselves forced to make a protected disclosure. The question is: why? They state they did so because of the wrongdoing they observed and the absolute hostility they encountered in the Garda culture. They too became whistleblowers, and they too were targeted and penalised. Ms Sweeney says that she was repeatedly pressured to close files prematurely. Dr. Corcoran says that after he made his protected disclosure he was targeted and forced out of his job, reassigned a different role, sent to an office on the other side of the building, given no real work and left to spend his day staring at the four walls. Why was Donal Corcoran so ruthlessly targeted and penalised? On whose order was Donal Corcoran removed from his job? Who repeatedly pressured Ms Sweeney to close files prematurely, and why? Why has this culture of hostility among the most senior management towards Garda whistleblowers been allowed to grow and go unchallenged? Members of the Garda go to work every day to protect us and they in turn deserve to be protected when they step forward to blow the whistle on wrongdoing. However, instead of being supported they are being destroyed. Following the disgusting treatment of Maurice McCabe we were assured things would change but more than a decade on, we learn that hostility towards whistleblowers and towards accountability at the highest echelons of the Garda is as bad as ever. Did any member of Government know about this? What action will the Taoiseach take to establish precisely what happened and what is currently going on within the Garda protected disclosures system? --- Source: Houses of the Oireachtas.
