35 Other pertinent recommendations in the UNODC/OHCHR Resource Book on the Use of Force and Firearms in Law Enforcement include:  he people affected should be informed of the decision to use containment • T against them, and the reason and purpose behind the decision. Continuous communication for the duration of the containment is recommended; and • Production of a press card should be reason enough to allow someone to leave, unless their behaviour justifies their containment.50 What monitors should observe and record • In what circumstances was the containment used? • Was the action targeted at people engaged in violence? Were people not engaged in violence affected? • Was force used to create the containment. Was force used after the containment had been established? • Were continuing threats made of the use of force? • How long did the containment last? • What was the weather like during the containment? • What was the effect of the use of this tactic (e.g., increased tension, panic, stampede, people collapsed?) • Were any of the people who were contained given the opportunity to exit (e.g., bystanders, media, non-violent participants)? • Were vulnerable people (e.g., children, pregnant women, persons with disabilities) contained? Were they given the opportunity to exit? • Did law enforcement personnel inform those affected of the reasons for their containment, and approximately how long the containment would last? • Were the people affected granted access to water, food, toilets and shelter? • Did law enforcement personnel collect personal information from those contained, perhaps as a condition to leave? • Were any of those contained arrested or further detained? • Was a warning issued before the use of containment? How much in advance of the use was the warning issued? • Was medical help provided (by the police, medical service) to those affected by the containment? 50 See: UNODC & UN OHCHR, Resource Book on the Use of Force and Firearms in Law Enforcement, op. cit., note 24, p. 121.
