. There was also a more secretive body called the Citizens Defence Force, responsible directly to Kevin O’Higgins and funded through the offices of Arthur Cox. In charge of it was Captain Henry Harrison, an Englishman who had been a meddler in Irish politics for many years. The exact function of this force remains unclear but some believe responsible for the unsolved disappearance of a number of prominent Republicans at that time. The remains of one of them, Noel Lemass, were discovered by accident years afterwards, secretly buried in the Dublin Mountains. Oriel House was taken over and became a much-feared interrogation centre. The team, about 80-strong, was accused of using brutal interrogation techniques and of the assassination of republican suspects and prisoners. A study of the period concluded,
"Oriel House succeeded in its task of suppressing small scale republican activities in the Dublin area, not by the sophistication and efficiency its intelligence work... but by the more direct method of striking terror into its opponents."
They were disbanded after the Civil War: supposedly because of squeamishness on the part of Kevin O’Higgins; but a core was retained as G-division of the
Dublin Metropolitan Police The Dublin Metropolitan Police (DMP) was the police force of Dublin in History of Ireland (1801–1923), British-controlled Ireland from 1836 to 1922 and then the Irish Free State until 1925, when it was absorbed into the new state's Garda Sío ...

The grades are based on a series of factors, including information supplied by international authorities.

Organisational structure

The Special Detective Unit operates out of the Dublin Metropolitan Region (DMR) Headquarters of the Gardaí in Harcourt Street, Dublin, and has personnel in all six Garda regions (DMR, Eastern, Northern, Southern, South-Eastern and Western). The unit has a number of secret buildings which it uses for covert operations. The SDU has a strength of between 200 and 300 plainclothes detectives, and a further 100 officers attached to the Emergency Response Unit. The agency is headed by a Detective Chief Superintendent, who is under the command of the Assistant commissioner in charge of the Crime & Security Branch (CSB), who reports directly to the Garda Commissioner. The Garda Commissioner briefs the Minister for Justice,
Taoiseach The Taoiseach (, ) is the head of government or prime minister of Republic of Ireland, Ireland. The office is appointed by the President of Ireland upon nomination by Dáil Éireann (the lower house of the Oireachtas, Ireland's national legisl ...

to prosecute terrorism offenders. The SDU is a highly secretive organisation that does its utmost to stay out of the media spotlight, and when officers from the unit appear in court they routinely give evidence anonymously from behind a screen to protect their identity. The budget for the SDU is classified, although it is drawn from the overall Garda budget (€1.34 billion in 2014). The only published figures are those for the budget to pay confidential informants, via the Covert Human Intelligence Sources (CHIS) system. The fund used to pay informers is known as the "Secret Service" budget, and it is shared between the Crime & Security Branch and Directorate of Military Intelligence. In 2014, it was €1 million.

The Garda Counter-Terrorism International (CTI) unit was established in 2014 as a dedicated section of the SDU to identify and monitor

Hostage Negotiation Section

The Garda Hostage Negotiation Section (HNS), officially formed in 2007, is a subdivision of the Garda SDU. It is headed by an experienced Detective Superintendent, who cannot be identified for operational reasons. The senior HNS officer along with the Garda National Negotiator Co-Ordinator (NNC) are involved in the selection, training and coordination of the more than 70 specialist Garda negotiators stationed in all divisions in the country. Officers under the command of this section are not necessarily Special Branch detectives. Negotiators are educated at the Garda Síochána College, Metropolitan Police Service,

Witness Security Programme

The Garda Witness Protection Unit is a small, dedicated and highly secretive subsection of the SDU, which operates the state's Witness Security Programme, at the direction of the Attorney General of Ireland. The unit (established in 1997) is headed by a Detective Inspector, and further reinforcements can be drawn from the Special Branch when there is a need. The Garda ERU provide tactical assistance to the programme. The budget for the unit was €1.198 million in 2014. Witnesses in the programme are given a new identity, address and armed police protection either in Ireland or abroad. There has never been a reported breach of security in which a protectee was harmed.

Killed in the line of duty

A number of officers in the Garda Special Detective Unit have lost their lives in the course of serving the state since the early 1920s. Seven Special Branch detectives are known to have been unlawfully killed in the line of duty since 1940.

Controversies


Electronic surveillance

It has been alleged that the Special Detective Unit has been involved in the telephone tapping and email hacking of crime journalists in Ireland, in attempts to reveal the identity of sources that appear in newspaper stories on crime and terrorism. A number of journalists have accused the unit of monitoring their electronic communications, as well as carrying out covert surveillance on them when they are meeting sources in person. Some journalists allege they have been questioned (and threatened with arrest) about sources used in crime and terrorism stories, including about Garda officers speaking to the media when not sanctioned to do so by senior management. Warrantless wiretapping by the authorities in Ireland is not illegal but in the absence of a warrant resulting evidence cannot be used to bring prosecutions in court. The press say they have been asked not to publish certain stories which may jeopardise sensitive Garda operations, but that the force has not attempted to influence reporting. In the month of January 2012 alone, Gardaí applied for 1,829 "requests for disclosure" from telecommunications and internet companies based in Ireland. There were 1,296 subscriber requests, 494 call trace requests and 39 IP (computer address) requests. Taken as an average monthly total, theoretically, Gardaí would be seeking details of over 20,000 phone and broadband subscribers per annum. These requests have been the subject of an investigation by the Office of the Data Protection Commissioner.
