Councillor Mary Fitzpatrick has said a "blame game" over security problems at the Swedish House Mafia concert in the Phoenix Park would serve no useful purpose.
Ms Fitzpatrick, Chair of the Dublin Central Joint Policing Committee, was speaking after concert promoter MCD issued a report yesterday criticising gardaí, whom it said failed to police the concert adequately.
"Engaging in a blame game at this point is counter-productive, it is not going to move things forward for MCD or the gardaí," Ms Fitzpatrick told RTÉ's Morning Ireland.
Seven people were stabbed at the concert and two men who had attended the concert later died of suspected drug overdoses.
Cllr Fitzpatrick said the aim was to ensure it never happened again.
She said: "Our objective as a city has to be to ensure that the city is an ideal venue to host major events, to attract in tourists and to support employment and social activity."
Ms Fitzpatrick discounted the necessity of a public inquiry. She also pointed to the improvements made for the Marlay Park concerts last month.
She also said the OPW had to address the issue of why it allowed three concerts in quick succession in the Phoenix Park.
Ms Fitzpatrick said improvements were being made: "There are specific tasks being undertaken to improve the combined risk assessment, the combined sign-off on deployment of garda resources and security.
“I think MCD, gardaí, OPW and Dublin City Council would admit that there were lessons learned. Now what we need to do is take those lessons and ensure that the required changes are made to the processes and protocols, and that's what we'll be driving through."
MCD blames cheap alcohol outside concert
MCD Chief Executive Denis Desmond has said he believes the availability of cheap alcohol outside of the Swedish House Mafia concert was a major contributor to the anti-social behaviour.
Speaking on the same programme, Mr Desmond said what happened at the concert in July was very disappointing.
However, he said it was only a small minority of people that caused trouble.
Mr Desmond said MCD was not blaming gardaí for the anti-social behaviour.
He said MCD has a great working relationship with gardaí and he said that he has great respect for the force.
But he said because of the good weather some people turned up early in the park and were consuming alcohol. He said this behaviour has to be stamped out.
