"Interim passivity" is the name of the method used when Swedish law enforcement waits for a limited time to intervene against crime that they would normally have intervened against. This is done due to tactical reasons in order not to disrupt ongoing covert surveillance operations. This study examines factors that influence the decision to use this method and postpone an intervention. This has been done using a qualitative method where six police officers with extensive experience in the field have been interviewed. The interview transcripts have been analyzed using athematic approach. Results shows that influential factors for postponing an intervention are the need to identify perpetrators and to map the different roles of individuals in criminal gangs. Results also shows that influential factors for intervening are danger to life and health, and that an intervention would be timewise favorable. Other influential factors are the credibility of the information and the possibility to intervene without uncovering the surveillance operation. In the discussion, a model of all influencing factors is presented. The importance of goodleadership is also discussed, and that the lack of guidance can lead to decision avoidance and omission bias.
