I am assuming that the Deputy's question relates to allegations of corruption involving members of the Garda Síochána.
In addition to the role of the Garda Commissioner in investigating allegations of criminality or misconduct relating to any member of the Force, the Garda Síochána Act 2005 has established the independent Garda Síochána Ombudsman Commission to investigate complaints made by members of the public concerning the conduct of members of the Gardaí, and regulations under the Act have established an independent Confidential Recipient to whom members of the Force can report, in confidence, instances which they believe may involve corruption or malpractice within the Force.
I have no reason to believe that allegations of corruption are not appropriately addressed.
