Recommendation MAI-139: Review and update JESIP Joint Doctrine

The Home Office, His Majesty's Inspectorate of Constabulary and Fire and Rescue Services, the College of Policing, the Fire Service College, the National Ambulance Resilience Unit and JESIP should review and, as necessary, update the Joint Doctrine: The Interoperability Framework (the Joint Doctrine) and Responding to a Marauding Terrorist Firearms Attack and Terrorist Siege: Joint Operating Principles for the Emergency Services (the Joint Operating Principles). The following matters should be considered in that review: a. achieving a situation in which commanders understand that the critical decisions of the commander most directly concerned in the issue under consideration are followed, unless there is a good reason for not doing so; b. achieving a situation in which risk appetite is common across the three emergency services - this will require collaborative work; c. achieving a situation in which forward deployment of specialist resources is the presumption, to be displaced only in the presence of a properly evidenced basis for not deploying resources forward; and d. achieving a situation in which the possibility of a secondary device does not delay forward deployment of resources, unless there is a proper basis for believing that such a device exists.
