In Third-Party Policing (hereafter TPP), police partner with others to proactively reduce crime and disorder, often focusing on places with recurrent crime problems, or people at high risk of offending. Partnerships in policing are not new. Police have always sought out and formed partnerships with a range of different entities to tackle a myriad of different types of problems. What is new for police is the expectation, and sometimes the legislated mandate, that they will partner with others. In the United States, the emphasis for police is on partnerships with communities to co-produce public safety (see President’s Task Force on 21st Century Policing, 2015). In the United Kingdom, police are compelled by law to involve local authorities in setting priorities and developing plans (see Police Reform and Social Responsibility Act 2011; Police and Fire Reform (Scotland) Act 2012), and numerous reports (see Independent Police Commission, 2013: 14–15; and National Debate Advisory Group, 2015, ch. 2) have expressed a vision for policing in which partnerships are central to most policing functions.
