The commission also made reference to the observed deficits in providing information and stressed the importance of informing detainees about fingerprinting and photographing measures and the further course of official processing. The police department reported that the process had been changed, so that official processing is now quicker. Once an interpreter arrives, general instructions are given before the start of fingerprinting and photographing measures, since written informational materials are often not understandable to the detainees.    2.7.5 Information regarding official processing Interpreters must be available. The initial questioning of traumatised persons must be done by professionals. Information about official acts must be provided expeditiously. Positive findings The commissions observed official police actions. As already mentioned at the outset, not all observations give rise to criticism. The police behaved in a highly professional manner at almost all football games, raids and events as well as several forced returns. The commissions passed this positive feedback on to the officials and their supervisors at the concluding meetings. The commission gave particularly positive feedback regarding the conduct of several named officials based on many observations. The NPM also informed the Federal Ministry of the Interior regarding them. Many police operations are properly carried out In one case involving a manifestation in Vienna, the commission asked to report its positive impressions directly to the police department of Vienna. The NPM gladly granted this request. The reason for this praise was – as in other cases – the de-escalating behaviour of the police through the use of the 3 D strategy. Potential troublemakers were expelled, and the police accompanied the manifestation in a loose formation without shields and helmets at a generous distance from the protest march. These tactics resulted in the manifestation proceeding smoothly. The discussions within the working group regarding the new Notification Decree were characterised by an open exchange of views and mutual trust with the goal of finding a joint solution. The fact that there was no substantial criticism of the information policy of the Federal Ministry of the Interior by the NPM as at the editorial close shows that this mutual trust has thus far been justified. 145 New Notification Decree
