Around 40 potential gangland hits linked to the murderous Hutch-Kinahan feud have been foiled by gardaí.
However, the force is solving significantly fewer violent crimes, including sexual offences, than before, the Policing Authority has heard.
Assistant Commissioner John O’Driscoll told an authority hearing organised crime groups are enjoying easy access to firearms.
But he said one of the force’s successes in recent times had been in relation to threat to life incidents, where he said many lives had been undoubted saved.
“There was an expectation when a particular feud between two gangs began that there were going to be numerous murders over a period of time,” he said.
“But instead what has happened is we have an ever increasing number, in the region of about 40 incidents, where we have prevented loss of life and where that has involved the seizure of firearms and the charging of people.”
However, other details to emerge from the hearing were less flattering for the force.
This included research which showed satisfaction among victims of crime in relation to the service they received was just 51pc.
The detection rate for sexual offences has also declined by 19pc, the hearing was told by authority member Judith Gillespie.
Deputy Commissioner John Twomey said he believed this was due to the “time lag” between offences being reported and investigations being completed and that he was confident the detection rate come year end would be similar to recent years.
