Sinn Fein president Mary Lou McDonald has said there is "no comparison" between IRA violence during the troubles and gangland violence.
Ms McDonald was speaking in relation to the former Sinn Fein councillor Jonathon Dowdall who was recently sentenced to four years in prison for facilitating the murder of David Byrne in the Regency Hotel in 2016. He has since turned state witness in the Regency murder trial.
Dowdall was also convicted of interrogating, threatening, and waterboarding a man in January 2015. The Dublin Central TD previously said she was "profoundly shocked" when she found out about the former councillor's gangland crime association.
