regard, the Federal Ministry of the Interior pointed out that operations of the Vienna police continue to utilise the principles of proportionality, accommodation of interests and the “3 D philosophy”. The Federal Ministry of the Interior conceded that errors can be made during difficult operations. However, individual events are always taken as a reason for improvement.     2.7.4 When the police encircled a crowd, the persons in the crowd must be given clearly audible information. Encirclement should be for as short a time as possible. Identifications must be processed as quickly as possible. An adequate number of computers is necessary for this. The successful 3 D strategy (Dialogue – De-escalation – Drastic Measures) should be retained and further developed. Compensatory monitoring measures in the border area So-called compensatory monitoring measures are compensatory measures for the purpose of monitoring illegal immigration and crossborder crime in the border area. Commission 3 observed some of these operations in the year under review. The commission conducted a detailed concluding meeting with representatives of the police department of Carinthia. The police department indicated that operations that apprehend more than ten persons have become more frequent. Large groups of persons are divided among the various police stations (Villach, Thörl Maglern and the Klagenfurt police detention centre), but families are kept together. When persons are apprehended in Styria, it will be possible to go to the next stop and process the persons in Leoben in the future. At the Klagenfurt police detention centre, separate rooms for the placement of about 15 persons apprehended in the course of compensatory measures have already been completed. The meals are governed by contract and provided by the Klagenfurt police detention centre or the Klagenfurt correctional institution. The commission criticised the fact that no interpreters were available at the time of the operation. They had to rely on bilingual persons who were acquaintances of the public officials. The initial questioning of traumatised persons is very difficult for both the interpreter and the official. Officials reported that they were frequently confronted with apprehending very young, severely traumatised and mainly female asylum seekers from Somalia and other North African countries and with Syrian refugees from war zones. There should be more officials available to do the questioning. 144 Good communication is important
