Looks like it's turning into a nightmare week for the Gardai. First we have the savage display of brutality which some members of the force engaged in and which was fortuitously caught on camera. Then the allegations in court that two officers had planted incriminating material in order to obtain convictions and procure promotions. Finally and potentially most disturbing of all, it now seems that the Gardai may have withheld information that could have prevented the Omagh bombing.
