Using data from a representative sample of the Dutch population (n = 656), we examined to what extent confidence in the criminal justice system, punitive penal attitudes and political orientation relate to public support for suspended sentences. Mediation and moderation analyses were done to further explore the dynamics behind public support for suspended sentences. Results showed that confidence in the criminal justice system, punitive penal attitudes and political orientation were related to public support for suspended sentences. In addition, support was found for our mediation and moderation hypothesis. In our conclusion we illustrate the importance of examining these factors in determining public support for suspended sentences.
