We remain committed to measuring the impact of participants on crime, anti-social behaviour and public perceptions of policing in partnership with independent analysts, both as a means of holding ourselves accountable for our activities and informing programme improvements. This is despite the widely acknowledged challenges of measuring impact6, limited availability of data on public confidence in policing at a neighbourhood level and the challenge of finding well matched comparison communities7. It is important to note that in the absence of a fully randomised design and without controlling for the other factors, the results presented here preclude any firm ‘cause and effect’ statements of impact8. The results in this report (and indeed previous reports and website materials) should therefore be treated with caution due to limitations with the data and methodology. This includes, for example, that police recorded crime and anti-social behaviour statistics can be affected by changes in recording practices and they only cover the incidents that come to the attention of the police. Further, it is important to note that like all officers, Police Now participants are subject to abstraction and often work on problem-solving activities beyond the boundaries of their dedicated neighbourhood area.
