The Garda Commissioner has said that An Garda Síochana's code of discipline needs to be updated.
Drew Harris told a meeting of the Policing Authority at Dublin Castle that the code is "ripe for modernisation and we are bringing that forward".
He said he could not say for certain that the behaviour highlighted by Mr Justice Peter Charleton in the Disclosures Tribunal report was isolated and he cannot be sure that it will not happen again.
It would, he said, be foolish of him to say so.
Commissioner Harris said that a serious deficiency was highlighted in the tribunal report and the risk of a negative culture breeding very negative behaviour still exists in the force.
The commissioner said people need to take responsibility and be held to account for the issues raised, and this is healthy for the force.
He aded that garda whistleblower Maurice McCabe did a great service in flagging up issues.
On Scouting Ireland, the commissioner said he believes that there will be multiple victims of sexual abuse in the organisation, and that the number of victims identified so far is "the tip of the iceberg".
Commissioner working on anti-corruption policy
Commissioner Harris said that he is working on an anti-corruption policy within the organisation.
He said management first needs to establish the extent of the problem and then design a policy to deal with it.
He said he wanted to make sure "we are on the right foot" as regards the approach.
Gardaí, he said, must have pride in the uniform, be visible and polite, and lead by example.
"We want to make sure the people we bring in and the people we have are unfailingly polite."
The commissioner said he was opposed to a "who you know not what you know" policy in the force and wanted to ensure there was a meritocracy in An Garda Síochána.
He said he wanted to make sure the promotions system is beyond reproach, he was changing the system to reflect this, and it would be reflected in the staff.
Commissioner Harris said the force's code of ethics has to be signed by people who seek promotion and before they begin their new roles.
He said he would expect those who seek advancement to be motivated by selfless service to the public and they want to be there for the right reasons.
The commissioner said he is focused on behaviours, corporate responsibility, An Garda Síochána's operating model, delegated authority, and giving officers the trust to make the correct and appropriate decisions.
He said he believed he would achieve cultural reform within five years but the institution will "outlast us all".
He said he has been thinking about how to open the organisation to more outside thinking and two places have been secured for gardaí on a strategic command course in the UK.
Commissioner says CAB successful in targeting low level criminals
Commissioner Harris said that local Criminal Assets Bureau initiatives have been successful in identifying low level criminals and depriving them of ill-gotten gains.
Drew Harris said that "it's all about the money" and that retrieving assets such as cash, cars and Rolex watches from criminals is important as it erodes their lifestyles.
He also said the seizures act as a deterrent as people look up to these criminals in a perverse manner having a lifestyle they wish to follow.
Commissioner Harris called on people to report unexplained wealth as there could be cases where individuals were living off criminal means and gardaí would be able to erode the confidence these people gain from a criminal lifestyle
Garda management also told the Policing Authority that it is introducing a new system to centrally manage criminal investigations across the country.
Deputy Commissioner John Twomey said the system will enable the organisation to determine the status of these investigations and ensure greater governance of the investigation of crime.
He also said that it will enable management to identify trends developing and introduce corrective measures if necessary.
Previously he said that criminal investigations were visible to those at district and divisional level but not nationally.
