This paper argues the current exposition of police knowledge through the discourses of police science and evidenced based policing (EBP) leads to exaggerated claims about what is, and can be, known in policing. This new orthodoxy underestimates the challenges of applying knowledge within culturally-mediated police practice. The paper draws upon virtue epistemology highlighting the role cognitive agency plays in establishing knowledge claims. We challenge the assumption that it is possible to derive what works in all instances of certain aspects of policing and suggest it would be more apt to speak about what worked within a specific police context.

Purpose -In England and Wales, on average one child every week is a victim of homicide. The purpose of this paper is to explore whether different victim risk profiles and suspect variables can be differentiated for specific victim ages.Design/methodology/approach -This paper presents a preliminary analysis of more than 1000 child homicides committed in England and Wales between 1996 and 2013, from data provided through the Homicide Index. Statistical techniques such as cluster analysis were used to identify specific victim risk profiles and to analyse suspect variables according to the age of victim. Findings -The findings present a clearer picture of the risk-age relationship in child homicide, whereby several specific risk profiles are identified for specific child ages, comprised of crime variables including; likely victim and suspect demographics, the most likely circumstances of the homicide and methods of killing. Using similar techniques, a number of tentative clusters of suspects implicated in child homicide are also described and analysed, with suggestions of further analysis that might prove of value.Originality and value -Although the statistical level of risk has been linked with the age of a child (with younger children being most vulnerable to killing by a parent or step-parent and older children most vulnerable to killing by acquaintances and strangers), extant research is yet to progress beyond the identification of broad age-risk categories. The paper concludes with a discussion of the likely implications for those charged with reducing and investigating child homicide and outlines the possibility of future research.

Recent decades have seen the sensitisation of UK society towards harm and policing ‘failures’ become increasingly significant. This paper is intended to stimulate thought and debate by analysing some consequences of these developments. It reviews literature in relation to risk-taking in UK operational policing, identifying increased criminal and disciplinary liability, particularly in respect of alleged omissions. Hindsight is found to be a potentially powerful influence. The article concludes that it is unlikely that public culture will be changed readily. However, police and other bodies should be able to reach a common approach towards operational risk, omissions and hindsight.
