© 2017, The Author(s). This paper sought the opinion of 200 Nigerians on their willingness to cooperate with the police during the Boko Haram crisis. Public perceptions of police effectiveness during the crisis, residence location, gender and religious affiliation were used as moderators. Data was analysed using an explanatory factor analysis and structural equation modelling. Results indicated a strong association between perceived effectiveness and willingness to report to the police with respondents who question the effectiveness of the police being less likely to be willing to report criminal activity about Boko Haram. Further to this, the impact of religion on willingness to report was at least partially mediated by perceived effectiveness of the police with the results showing that Christian respondents perceived the police as less effective. Females and those living in the nor th were significantly less willing to report criminal activity to the police. The findings are discussed in relation to the BH crises and directions for future research are given.
