Parts III and IV of the book address issues reflected in the Commission's terms of reference to do with relationships, delivery and resourcing. Chapters in Part IV take us into the territory of what has been termed ‘high’ and ‘low’ policing (Innes and Thiel, 2008). The latter is concerned with the everyday protection of the citizen and largely reacts to notification that a crime or some disorder is in progress or has taken place. The former is about matters that threaten the security of the state and is often proactive, involving infiltration, surveillance and intelligence gathering and analysis. What Innes and Thiel make apparent is that clear-cut boundaries between the two have changed over time and that having a national capability represents a departure from the local delivery and accountabilities of Peelian modes of policing said to characterise the British Model of Policing. The blurring of boundaries is reflected in the chapters in Part III with discussions of public-private provision.
