In the Republic of Ireland, almost 1,000 officers from the Garda Síochána mounted a security operation along the border.[20] Eight temporary border checkpoints were manned by Garda units backed up by the Irish Army.[21] The Garda's elite tactical team, the Emergency Response Unit (ERU), and the special operations forces from the Defence Forces, the Army Ranger Wing (ARW), were deployed on land and water to secure the border from unauthorised crossings.[22] Some of the delegations attending the summit stayed in the Republic,[21] and protesters announced their intention to hold demonstrations in Dublin. Like in Northern Ireland, a special court had also been set up in the Republic to deal with protesters who were arrested there.
