This is the report of the proceedings of the ‘Policing in Changing Policy Environments’ event held in Dublin Castle on the 11th June 2019. The event brought together 40 national and international delegates who work at the intersection of law enforcement, public health and community safety. The event was held under the Chatham House Rule, and this report has been developed consistent with that rule. What is reported on are the themes and key issues that were discussed, but no individual or organisation has been identified as making any particular statement. This report has been developed from two main sources of information – Ana Liffey Drug Project staff members who organised the event and took notes on the day, and the produce of the graphic facilitators. The report is a short collection of the key insights, topics and reflections from the event. It is not intended to be an exhaustive documenting of the day, but is rather an attempt to frame the key issues and themes that energised delegates on the day. It was prepared by the Ana Liffey Drug Project and was circulated amongst all delegates for input before finalisation.
