Normbeelden als alternatief voor politiecultuur: de integere, neutrale en loyale supercop

Tijdschrift Tijdschrift voor Veiligheid, Aflevering 0203 2016
Trefwoorden police culture, norm image, integrity, neutrality, loyalty
Auteurs Sinan Çankaya
SamenvattingAuteursinformatie

    This article argues that the notion of norm images does more justice to the complexity of the police organization. The notion of ‘police culture’ is heavily criticized for its homogenizing tendencies, monolithic connotations and stereotypical and negative evaluation of police work. Norm images have an analytical value, because (1) the images are contextualized within and connected to the rule of law, (2) the images are sufficiently analytically flexible for a situational and relational interpretation of the cultural processes within the police organization, and (3) the notion theoretically presupposes the resistance strategies of social actors against the norm images. The article illustrates the theoretical value of norm images by focusing on the dominant images of the ‘trustworthy’, ‘neutral’ and ‘loyal’ police officer.

SamenvattingAuteursinformatie

    To improve security in crowded environments, such as airports, shopping malls and railway stations, the number of surveillance cameras (CCTV) is rapidly increasing. However, the number of human operators remains limited and only a selection of the video streams can be observed. This makes it hard for an operator to be proactive. This paper gives an overview of novel developments that may lead to more efficient camera surveillance and a more proactive role for camera operators. It focuses on three main steps in this process of video content analysis: pedestrian tracking, action recognition and behavior analysis. Tracking and re-identification (i.e. recognizing a person in another camera) was initially only evaluated on off-line benchmark datasets, though recently it has gained in maturity with live demonstrations in realistic crowded environments and measured improved operator efficiency. For action recognition and automatic behavior recognition, we observe that the simple patterns, such as loitering detection, are emerging in many applications. Human action recognition obtains very high performance values in controlled environments and it is progressing towards more realistic environments. More advanced approaches, such as pickpocket recognition in a shopping mall and the detection of threats to trucks on a parking lot have been developed and the first systems have been presented in live demonstrations. Our main contribution is that we structure the recent advances and the emerging applications of video analysis for security applications, explain and interpret the results, and identify opportunities for the near future.

    In 2011 we executed a quantitative and qualitative research on the extent of discrimination, polarisation and radicalisation in a region in the Netherlands. The results are representative for The Netherlands. The research shows that there is breeding ground for radicalization, in particular Muslim youths. The outcome also provides insights in relevant avenues for public policy. Over the past years, several inventories have been made of public policy that aims to counter radicalisation. Most of the interventions listed do not conjure with the interventions we propose on the basis of our research, such as awareness raising for practitioners, prevention of and education about discrimination, focus on neighbourhood grievances and nuisances caused by specific ethnic groups and the negative tone of the public debate regarding Islam and the multicultural society. If measures to counter radicalization are even evaluated, they tend to focus on the process and effectiveness of the intervention, but they do not answer the question if that is actually also the right intervention. We therefore propose not only to focus on doing things right, but also to ask the question if we are doing the right things. We suggest not only measuring effectiveness, but also measuring impact.
