    The Mobile Security Monitor (MSM) is a form of migration policing in the border areas of the Netherlands, carried out by the Royal Netherlands Marechaussee (KMar). The MSM has a complex legal and policy framework, merging migration control aims with certain elements of crime control. This raises the question how the officers carrying out the MSM interpret the exact aim of the instrument and their own accompanying powers and what this means for the way they carry out their task. Our results show that many officers see ‘catching criminals’ an important part of their job and that in order to achieve this, they sometimes make ‘creative use’ of their wide-ranging powers. Although similar results have been found in research with the police, KMar officers differ because of their ability to combine migration law and criminal law powers. This fits in with the process of crimmigration and the broader tendency of ad-hoc instrumentalism, which refers to a way of thinking about law and legal procedures in which the formal distinction between legal domains is considered less important and criminal justice actors can freely choose the most effective instrument to deal with the situation at hand. This means that the formal ground for a decision is not always transparent, especially not for people that are subjected to the MSM. Moreover, criminal law enforcement contains many more legal and procedural safeguards than administrative controls.

    A single observation of deviant behavior by security officers often provides insufficient information about potential malicious intentions of individuals. This article shows that combining multiple security officers’ observations of deviant behaviors leads to better judgments about possible malicious intentions than judgments of individual officers. In the study described in this paper, experienced supervisors viewed CCTV images of a mall in which pickpockets were active (in reality these pickpockets were confederates). Participants could tag individuals in the footage if they felt that these individuals portrayed deviant behaviors. Using statistics based on signal detection theory, we calculated the accuracy with which individuals in the footage with hostile intentions (i.e., our confederates) were distinguished from individuals without hostile intentions (i.e., the general public). We compared the aggregated individual accuracy scores of participants to accuracy scores of combinations of 2, 3, or 4 participants. Results show that combining observations from two participants leads to higher accuracy than observations of individual supervisors. This effect is mainly caused by an increase in hits (correctly tagged pickpockets). As observations of more participants are added (viz., combinations of 3 or 4 participants) accuracy stagnates. This is mainly caused by an increase in false alarms (judged hostile by participants, but in reality innocent visitors). Implications are discussed for organizations in the security domain and for further research.
