In three days' time, we will recall the second anniversary of the callous killing of Detective Garda Adrian Donohoe in the community of Lordship in north Louth. It is only right, proper and appropriate for us to do so. It is difficult to believe that two years have passed since that happened. Tempus fugit, time flies. It is difficult to accept that the callous killers are still at large.

The Minister, Deputy Frances Fitzgerald, and the Garda are totally committed and focused on ensuring the killers and perpetrators are tracked down as soon possible. We are all aware that the killing of a detective garda in the course of his or her duties is a callous and serious crime.

Hear, hear.

The investigation is ongoing on a daily basis. The Garda is totally focused. Once again, I appeal to anyone who has information that could bring this investigation to fruition to speak up. Co-operation between the Garda and the PSNI is to be applauded but we need the help and support of individuals in south Armagh and in north Louth. They can use the confidential lines to ensure the perpetrators are brought to justice as soon as possible.

I join with Senator Brennan in calling on the public of south Armagh, north Monaghan and north Louth who have information about the killers of Detective Garda Adrian Donohoe or the brutal murder of young Paul Quinn not to be intimidated by the criminal gangs operating in the area and to come forward and help the Garda and the PSNI with their investigation. Those monsters cannot be tolerated in any modern civic society. They have no place in it. The same is true of those who callously murdered Garda Jerry McCabe in Adare in my constituency and who tried their best to murder Garda Ben O'Sullivan when both men were carrying out their duties as members of the police force. Those people have no respect for law and order. They are a law unto themselves. They operate with impunity through intimidation and psychological harassment. That cannot be tolerated as it has no place in society. I commend Senator Brennan on bringing this issue to the fore. I support his appeals to the people of those areas not to be afraid and to come forward with information that will nail the people who carry out such acts.
