The Minister for Justice has expressed his concern at recent serious criminal activity in Limerick.
However, Mr McDowell maintained that all the necessary resources were being directed towards tackling what he termed such "outrages".
The Minister made his comments yesterday at the official opening of Limerick's newly refurbished County Circuit Courthouse.
He said he had discussed the recent upsurge of serious crime in Limerick with both the Garda Commissioner, Mr Pat Byrne, and Chief Supt Gerry Kelly.
Following the recent murder of 23-year-old Mr Robert Fitzgerald, the Minister for State for Justice, Mr Willie O'Dea, called for the redeployment of the Garda Emergency Response Unit to the city.
However, the Minister for Justice said yesterday there were no "quick-fix solutions" to tackling crime, and time was required to gather evidence and prepare cases.
"I am determined that criminal activity as recently displayed will be tackled with all the resources at the State's disposal," he said.
"The Garda authorities have already taken specific additional measures in the Limerick area and they will continue to take a proactive approach to ensure outrages will not continue."
Mr McDowell was speaking ahead of the first sitting of the Central Criminal Court in Limerick on July 8th.
The move is due to the backlog of murder trials, where the accused are from Limerick, waiting to be heard before the Central Criminal Court.
It is expected that transferring the court to Limerick will help maximise Garda resources, as each trial would involve a considerable number of Garda witnesses.
The Central Criminal Court is also scheduled to sit in Limerick for the next legal term in November.
"To conduct these trials in Limerick will lead to less cost, less inconvenience for civil witnesses and, most important of all, result in gardaí having to spend a much lesser amount of time away from their normal policing duties," said Mr McDowell.
The Minister was joined at the official opening of the courthouse by Mr Justice Murray of the Supreme Court.
The Mayor of Limerick, Mr John Cronin, and the Cathaoirleach of Limerick County Council, Ms Brigid Teefy, were also present.
Limerick Circuit Court House, which was first built in 1810, was refurbished over an 18-month period at a cost of €10 million.
The original roofline, which was removed in the 1950s, has been restored, allowing for an extra floor of accommodation to house the offices of the County Registrar and his staff.
