Guardianship, Reactive and Preventative
Ideally, crime and disorder are not prosecuted; they are pre-empted. Yet the police cannot (and should not) be everywhere. For the maintenance of social control, community guardianship is critical. Guardianship, a key element of informal social control, is central to two influential theories in criminology and sociology: routine activity theory and collective efficacy. Two distinct forms of guardianship, reactive and preventative, should be distinguished. Reactive guardianship involves an individual or a small group responding to an ongoing criminal incident or a potentially harmful situation for the purpose of disrupting it. People balance prosocial motivation to help others against safety and social costs associated with intervening. Preventive guardianship involves action by community members that prevent crimes from happening in the first place—the ideal outcome. My Max Planck Law Fellowship has focused on the decision-making process of private citizens to serve as both types of guardians. In the case of preventive guardianship, the research also focuses on the conditions under which it can be effective in preventing crime.
The Max Planck Law Fellow Group is headed by Professor Dan Nagin and brings together researchers from and under the direction of Professors Christoph Engel and Jean-Louis van Gelder.
