Many strange things happened in the
  administration of justice during the '70s, particularly within the operations
  of the garda Siochana. It was a difficult time, with many fearing that the
  institutions of the State were under real threat from the re-emergence of the
  IRA, and with many atrocities being carried out in Northern Ireland and,
  occasionally, in the south. This led to abuses of power by small sections of
  the gardai, particularly the operation of the so-called "heavy
  gang". Cooperation between the security forces on both sides of the
  border was closer than many credited and efforts were made to gather
  intelligence from every possible source. One of the best ways of doing this
  was to use informers, but, it appears, informers may have been caught up in
  actions which were illegal but which they felt were necessary to establish
  their bona fides and, in the long run, save other lives.
  But it is hardly acceptable that, in the
  so-called name of the greater good, innocent people died and that then their
  killers were allowed to escape for reasons which had nothing to do with the
  proper administration of justice. This, it is now suspected, is what happened
  in the case of Seamus Ludlow, the Louthman murdered by loyalist terrorists
  (who also benefited from protection from the British authorities) in 1976.
  Even worse, it is claimed that the Irish authorities colluded in a cover-up
  and, not satisfied with that, implied erroneously that Ludlow was an informer
  and that he was shot by the IRA for this reason. For the sake of Seamus
  Ludlow's family, and to maintain confidence that one of the most important
  arms of the State has acted honourably and correctly, a full investigation is
  required into the circumstances not just of his murder but also the
  investigation which followed it.
