ACPO

The Association of Chief Police Officers is responsible for defining national standards and professional practice in key areas of policing. Standards and practice provide a framework which supports accountability, interoperability and improvement in working practices across the police service and its partners. In high risk areas of policing they help ensure consistency of approach, underpin training and business processes and thereby better protect the public. All standards and practice are agreed collectively by Chief Constables through ACPO Cabinet and Council before adoption. ACPO guidance and practice advice defines nationally agreed good practice for forces, but accountability as to whether to adhere to such guidance rests with chief constables who are operationally independent.
There is, for example, the ACPO Code of Practice for Operational Use of Road Policing Enforcement Technology. This has in recent years provided guidance for implementation and correct use of items such as radar and laser speed camera devices. It is currently in abeyance as it is being redrafted.
