In cultural criminology, we talk about crimes as secrets and secrets as crimes. There is a close relationship between criminality and secrecy. The unravelling of secrets can help us discover the meaning criminals attach to their actions and contacts. Secrets have always been a topical issue, as they are strongly embedded in our social world. Secrecy used to be functional in times of war and under dictatorships as a symbol of political and/or religious protest. Today, however, secrecy is most often associated with illegality and criminality. It is not easy to study secrets and secrecy, and for this reason criminological research requires specific, mainly ethnographic, research methods.
