What is no body no crime about?

"No Body, No Crime" is a phrase often used in criminal investigations when a person goes missing and there is no physical evidence or body found to indicate a crime has been committed. It means that without a body or other evidence, it is difficult to establish that a person has been killed or harmed, and therefore difficult to prosecute anyone for the crime. This phrase is particularly relevant in cases where someone may have been abducted or murdered and their body may have been deliberately hidden or disposed of in a way that makes it difficult to find. The phrase is often used in true crime and mystery genres to describe the challenges investigators face when trying to solve a case without any physical evidence.
