The chairman of the Garda Ombudsman Commission says he has no intention of stepping down.

Simon O'Brien's defended the decision to investigate several 'anomalies' in the IT and security system at GSOC's offices.

That's despite the finding of the Cooke report, which says GSOC's investigation into the security issues was unnecessary.

Simon O'Brien says some "question marks still remain" - and he has no plans to quit:

The report finds simple explanations for two of three security issues found by GSOC, while the other is described as a technological anomaly.

Our Political Editor Shane Coleman told Newstalk's Breakfast O'Brien's likely to stay on in his position:

The justice minister last night said she still has confidence in the Garda Ombudsman Commission.

In a statement, the Ombudsman Commission says the findings mirror its own investigation which stated in February that they were satisfied their databases were not compromised, and there was no evidence of garda misconduct.

The Commission agrees with John Cooke that a counter surveillance operation should be run on their office more often.

Minister Frances Fitzgerald says although the report is critical of GSOC, its members did get some credit:

The minister also defended her predecessor Alan Shatter - saying  the report offered "food for thought" for people who had criticised him when the reports first emerged.

But there are dissenting voices, UCD law lecturer TJ McIntyre has revisited concerns voiced by GSOC officers:

While Fianna Fail's Justice spokesman Niall Collins agrees some aspects of the report which are inconclusive:

Smoke and mirrors

Meanwhile, interim Garda Commissioner Noirin O'Sullivan said she - and her senior management team - are conducting a close review of the document.

Last night she also said the force acknowledges that the working relationship between the force and GSOC needs to be more constructive.

And the Garda Representative Association has welcomed the findings of the Cooke report, though they highlighted their concern that the issue of the security and personal safety of individual gardaí was not raised.

The human rights watchdog says there appears to have been no attempt to establish objectively whether or not surveillance of GSOC by gardaí had been sought or authorised.
