Monitoring is done as an early warning mechanism, during incidents and for monitoring the effects of LEA actions.
LEAs use (clusters of) keywords and/or geographic searches on open soclal media sources to understand what’s going on and monitor theme, location or event based threats.
During events, LEAs use tools to analyse mood and sentiments. The Police Service of Northern Ireland, regularly monitors social media for large scale events. The PSNI use Hootsuite Insights, Facebook and Twitter.
