Will the garda/ the Garda Síochána find out that I complained about them?

If your complaint is investigated, Garda Headquarters and gardaí involved may be given any information on your complaint form (including your name), in the course of the investigation. If your complaint cannot be dealt with by GSOC however, they will be notified that a complaint was made and the nature of it, but will not be given the details (including your name).
