SIS should contain alerts on missing persons or on vulnerable persons who need to be prevented from travelling to ensure their protection or to prevent threats to public security or to public order.
Ba cheart foláirimh a bheith in SIS maidir le daoine atá ar iarraidh nó maidir le daoine leochaileacha is gá a chosc ó bheith ag taisteal chun a áirithiú go ndéanfar iad a chosaint nó chun bagairtí ar an tslándáil phoiblí nó ar an ord poiblí a chosc.
