Based on extensive qualitative research with a murder team, and interviews with detectives involved in the original inquiry, the article describes how the events surrounding Stephen Lawrence's murder and its investigation were 'framed' in very different ways. In one account race and institutional racism were central, in the other they were peripheral. Although denial of racism was a key feature of detectives' discourse, their knowledge of murder investigations also led them to challenge criticisms made of the investigation - some of which were supported by the research. However, it was also apparent that detectives were generally unaware of the potential for unwitting or discriminatory behaviour in their investigations.
