In the recent years, police violence and discrimination towards minorities have become widely criticized by news outlets and within society. The trust in the police has decreased over the last years as ethnic profiling and the deaths of multiple people of colour have come to light. The police law enforcement and their officers have been criticized for their behaviour, as there has been a disproportionate number of arrests targeting people of minority. However, studies researching the occurrence of discrimination in police law enforcement and its effects, have not been conducted in The Netherlands. This study aims to identify which factors influence a police officer’s decision, as this arguably has the most impact on a citizen, and whether discrimination can occur in these factors. The first step is to identify the factors, which is achieved through a literature review. As not much research is performed in The Netherlands regarding discrimination in police law enforcement, multiple interviews are held with police officers to verify the obtained factors from the studies. This resulted in five factors being identified, namely type of crime, ethnicity, gender, familiarity with the police and group size. The above mentioned factors are used in the survey, which was distributed among the police officers stationed in the bureau Haarlem, North-Holland. The factor ethnicity influences a police officer’s decision for citation. However, contrary to the results obtained from the literature, a Non-Western individual is not more likely to be arrested compared to a Western individual. This study found the exact opposite; an individual of Non-Western ethnicity is less likely to be cited compared to a Western individual. The relative importance of this factor is however very small as it contributes for less than 5% on the decision of a police officer for citation. The other factors that influence a police officer’s decision for citation in this study are mixed gender and type of crime, with a relative importance of less than 8% and 87% respectively. The factors group size and familiarity with the police are not statistically significant, which means that they do not influence the decision of a police officer. There are multiple limitations in this study. First, this study was conducted with a limited number of respondents and hence it is hard to generalize to the population. Secondly, the study was conducted with police officers stationed only in Haarlem, therefore hard to generalize to the police officers in The Netherlands. Thirdly, the results may have been exposed to hypothetical bias. Lastly, the research method can be seen as a limitation as this method is used for consumer preferences and not to explore moral considerations. Lastly, this study provides four recommendations for further research. Firstly, more research must be conducted with regard to discrimination in police law enforcement. Secondly, respondents participating in the study should be increased and multiple bureaus should participate to be able to generalize the results. Thirdly, future research should incorporate the police officer’s educational level. Individuals, who have experience in critical thinking, rely less on profiles in their decisions. Lastly, by identifying heuristics and shortcuts, and researching whether these methods contain possibilities for discrimination to occur, is valuable knowledge to obtain to succeed at the aim of policing for everyone.
