When witnessing a situation of an
victim and 'incriminator', the degree of responsibility the witness has in helping the victim or stopping the 'crime' in progress. The degree of responsibility usually depends on three criteria; 1. Whether the victim is deserving of help, 2. The competence of the bystander, 3. The
relationship between the bystander and the 'victim'. The bystander can intervene in usually two
different ways; direct intervention, or, calling authorities.
