Garda representatives have welcomed the O'Higgins report 'categorically ruling out' Garda corruption and criminal conduct
Garda representatives say police work is suffering due to staff shortages.
The warning follows yesterday's publication of the findings of the O'Higgins Commission - which examined alleged Garda malpractice in the Cavan/Monaghan division between 2007 and 2008.
In his review, Judge Kevin O'Higgins criticised how some cases have been handled and how some victims were treated by investigators.
However, he found no evidence of Garda criminality or corruption.
James Morrisroe, of the Garda Representative Association, says funding shortages are making their jobs even harder.
Mr Morrisroe told Newstalk Breakfast that "in the Cavan-Monaghan division we're down 22% in relation to members, so the situation here is critical in relation to frontline members.
"We just don't have enough guards to sustain the police work we have to do," he added.
The report into claims of garda malpractice and corruption found that former Justice Minister Alan Shatter had taken the allegations of whistleblower Maurice McCabe “very seriously”.
Mr Shatter has called on Taoiseach Enda Kenny to correct the Dáil record following the release of the O’Higgins report.
