Sir Robert Edward Graham Shillington CBE (2 April 1911 – 14 August 2001) was a senior Northern Irish police officer.
When the Battle of the Bogside broke out in Derry City in August, Shillington asked for permission to use CS gas for the first time in the United Kingdom.
[2] He had to telephone Peacocke in order to persuade him of this, on 13 August; the latter, who had long denied the need for army involvement, eventually agreed, but his reputation never recovered and following the publication of the Hunt Report in October he resigned as Inspector-General.
Young's measures introduced the standard British rank system for police officers in Northern Ireland and disbanded the Ulster Special Constabulary.
[citation needed] Shillington remained as Young's deputy, and when the latter returned to the mainland in 1970 he succeeded him to become the RUC's second Chief Constable.
