Fianna Fáil is calling for more Garda resources to crackdown on gangland crime.
The Justice Spokesperson for the party is Dara Calleary and he said Irish legislation is tough enough but cutbacks have had an impact on case-building.
Mr Calleary said: "Gardaí will tell you that they are on the way to preparing cases - for what's involved is man hours, or garda hours.
"For instance supervision or surveillance on any of these people - that's the way you're going to get them; by sitting in their faces, by being on their doors, being on their tail every time they move".
"That's the way you get them, that requires costs."
It comes after the discovery of the bodies of two men found dead in a burned out car at a Co Louth forest.
DNA and dental records are expected to be used to help identify two men found dead yesterday.
They were discovered in a car that was set on fire near Ravensdale forest on Wednesday, and it is believed they had been shot before the blaze started.
The heat was so intense that Gardaí had to use the chassis number of the car to establish any details of the vehicle.
The men's deaths follow the fatal shooting of two other men in an incident in Kilcock County Kildare earlier this week.
