English: "[The Parties undertake]...to facilitate close co-operation and exchange of appropriate information between the police forces of the different localities involved or likely to be involved".  This provision is supplemented by Article 4 of the Convention, which provides for international co-operation in this sphere.  On the basis of the principles of the Convention, a number of initiatives have already been taken by the Standing Committee.  2. Activities of the Standing Committee (T-RV): In accordance with Article 9 of the Convention, the Standing Committee has made recommendations and proposals to the Parties on measures to be taken in order to implement the Convention.  In its 1988 Recommendation on police co-operation, the Standing Committee advocated the use of police "spotters" working in an advisory capacity to identify troublemakers or provide advice as to signs of trouble developing at major international sports events:  a. On the use of advisory police "spotters"  That, on the occasion of major international sports events where spectator violence is to be feared, the police authorities from the countries of the participating teams discuss the possibility of arranging for advisory plain-clothes policemen from the visiting country(ies) to assist the police force(s) responsible for the match(es) on potential problems from the visiting supporters (for example, help in identifying known troublemakers, advice on signs of trouble developing).  b. On preparations for major events  That the relevant police authorities consider organising before major international competitions training seminars for senior police officers on the organisation of crowd control measures (before, during and after matches).  In the area of international police co-operation and in accordance with Article 4 of the Convention, comprehensive guidelines were adopted by the Standing Committee in its 1991 Recommendation.
French:   Dans sa Recommandation de 1988 sur la coopération de la police, le Comité permanent préconisait le recours aux services consultatifs de policiers "observateurs" pour identifier les fauteurs de troubles ou pour disposer des renseignements sur l'imminence d'incidents lors des grandes manifestations sportives internationales:   a. En ce qui concerne le recours aux services consultatifs de policiers "observateurs"  Qu'à l'occasion des grandes manifestations sportives internationales où il y a lieu de craindre des phénomènes de violence de la part des spectateurs, les forces de l'ordre des pays d'où proviennent les équipes participantes étudient la possibilité de demander à des policiers en civil originaires du ou des pays invités à conseiller le ou les services de police chargés de ces rencontres des problèmes potentiels que pourraient poser les supporters visiteurs (par exemple en les aidant à identifier des fauteurs de troubles notoires ou en les renseignant sur l'imminence d'incidents).  b. En ce qui concerne la préparation de grandes manifestations  Que les forces de police compétentes envisagent d'organiser, avant les grandes rencontres internationales, des séminaires de formation à l'intention des responsables de la police sur les mesures à prendre pour maîtriser les foules (avant, pendant et après les matches)  Dans le domaine de la coopération policière internationale et conformément à l'article 4 de la Convention, des orientations plus complètes ont été adoptées par le Comité permanent dans sa Recommandation de 1991.
