Getting into the scenario on the day in question, at what time did Mr. Harris realise there was a serious problem? Was it after 1.30 p.m., when the incident happened outside the school, or was it when the first of the 13 Garda cars were burned? Was it when Dublin Bus said there was a conflict zone in Dublin city centre or was it when gardaí went around restaurants and pubs and told them they would have to empty?
