Policymakers have a duty to base their decision making in the best available evidence relevant to the question at hand. This paper discusses why it is important for policymakers to recognize the valuable contributions to be made from within the fields of investigative and forensic psychology and particularly to inform the process of policymaking and legislative frameworks currently in place regarding suspicious approaches to children offences in the Irish Criminal Justice System. Discrepancies between legal and psychological considerations infer potential issues with policymaking; resulting in evidence‐based concerns regarding how suspicious approaches to children are handled. It is argued that in cases of suspicious approaches to children, important research is available within the fields of investigative and forensic psychology that warrants adequate consideration by policymakers. Additionally, the need for further collaboration between policymakers, researchers and front‐line enforcement agencies to ensure evidence‐based approaches for dealing with suspicious approaches to children and other criminal behaviours within the Irish criminal justice system is highlighted.
