This chapter examines how the public order script, explored in Chapter 6, was performed by commanders. It begins by exploring how commanders sought to sell the script to the parade and protest groups commanders sought to ‘win over’. If such groups could be won over with the PSNI’s pitch, the likelihood of disorder was greatly diminished, and commanders could better control the event. In some cases, however, the sales pitch proved unsuccessful; marchers and protestors proceeded with their own agendas. In such instances, commanders proved reluctant to intervene too forcefully, for reasons that will become clear. In two high-profile cases, the police approach to disorder has led to legal challenges, both of which reached the UK’s highest court. This introduces the second audience occasionally in receipt of the police script: the courts that must assess the internal self-application of human rights law by police. In their review of police decision-making in these cases, though, the senior judiciary have proven reluctant to interfere, showing deference to officers’ relative expertise, their access to intelligence and the exigencies of operational situations. The final section asks what role human rights law has come to play in managing the kinds of ‘trouble’ that Waddington (1994) identified over two decades ago as crucial to commanders’ decision-making.
