Two garda associations have rejected assertions that the Government has supported the fight against organised crime.
Earlier today, Taoiseach Enda Kenny told the Dáil that the Government is committed to cracking down on organised crime in the wake of recent gang murders.
Following yesterday's fatal shooting of Gareth Hutch in Dublin, Fianna Fáil leader Micheál Martin said the State needed "to get into the face of the criminals and make sure crime did not pay".
The Taoiseach said every effort was being made to bring the perpetrators to justice.
However, Mr Kenny said it would take time because of the international element involved in the feud that had already resulted in the deaths of seven people.
The Association of Garda Sergeants described Mr Kenny's assurances as "rhetoric" while the Garda Representative Association said the police service has major difficulties in relation to resources, manpower and training.
The AGSI said there are 140 fewer gardaí in the Dublin North Central division, which covers North Cumberland Street, the location where Gareth Hutch was shot, than there were four years ago.
AGSI General Secretary John Jacob said the Government has not delivered but has demoralised the force by cutting pay and creating a two-tier pay system.
Meanwhile, the GRA said only a quarter of specialist detectives investigating organised crime are trained to question suspects.
GRA President Ciaran O'Neill said the force was around 3,000 to 4,000 member short of where it should be.
Speaking on RTÉ's News at One, he said this was a direct result of years of neglect and the moratorium on recruitment.
Mr O'Neill said that this situation is likely to get worse due to impending retirements from the force.
He added that gardaí need to hear that recruitment will be accelerated and that pay issues would be dealt with as a matter of urgency because morale in the force was at an all time low.
A man was arrested last night in connection with yesterday's murder, the seventh in the dispute between the Hutch and Kinahan criminal gangs.
Gareth Hutch, who was in his 30s, was shot dead at around 10am as he was about to get into his car outside his home on North Cumberland Street.
He was known to gardaí for his involvement in serious crime and was charged a number of years ago in connection with an armed robbery during which another man was shot dead.
He is also related to Gary Hutch, the first victim of the feud with the Kinahan drugs cartel, who was killed in Spain in September 2015.
At 7pm yesterday a man in his 20s walked into Mountjoy Garda Station and handed himself in.
He is now being detained in connection with the murder of Gareth Hutch under anti-gang legislation and can be questioned for up to a week.
Gardaí have also appealed for information about a silver Skoda car, registration 05 D 15049, which was seen on Sean McDermott Street at about 10am, following the murder of Gareth Hutch.
The was later seen on Rutland Street Lower before being found burnt-out in the Dubber Cross area of Finglas.
Two other men are also still being detained in connection with two other feud murders - one in relation to the murder of Eddie Hutch, Gareth Hutch's uncle, the other in connection with the shooting of David Byrne, who was murdered at the Regency Hotel last February.
€5m available for armed response unit - Donohoe
Earlier, Minister for Public Expenditure and Reform Paschal Donohoe said the Government will spare no effort in bringing those responsible for recent shootings and murders in Dublin to justice.
Mr Donohoe said €5m has been made available for an armed response unit and funding is in place for garda overtime and equipment.
The Dublin Central TD said the recent murders have shocked, appalled and threatened communities that he lives in.
Speaking on RTÉ's Morning Ireland, he urged anyone with information to come forward and said that local co-operation will be crucial in helping gardaí.
Providing officers with resources and reform is the only way to address the issue and this is being done, he added.
"It's that kind of local co-operation that is crucial to the gardaí responding back to this. We have a track record, that's happened for example in Limerick, of bringing people to justice who commit these crimes," said Mr Donohoe.
"We will continue to work with An Garda Síochána to do the only thing that matters to people - and can deter people who threaten us - which is resources and reform for the guards."
When questioned about changes to the way the annual budget process works, Mr Donohoe said that a year- round budgetary process will mean the Government is better able to hear the views of opposition parties and independent TDs, but crucially, that those in opposition will be given more information and tools.
He added that the Government needs support for budgets to be implemented and that this means there will not be any major surprises on Budget day.
The minister said that this means budgets, that can build on the changes in the economy, can be passed.
