In this episode, former Western Australia police diver Luke McCulloch returns to discuss the realities of his eight years in the dive squad, sharing frank details about body recovery, dangerous environments, and encounters with sharks. The guest and host examine the psychological mechanisms divers use to survive harrowing assignments, such as treating remains as objects and avoiding learning personal details about victims, while also addressing the emotional toll that eventually led to seeking professional help for post-traumatic stress. What makes the conversation compelling is the unvarnished look at specialized police work, stripping away cinematic myths to reveal the gritty, meticulous nature of black-water searches and underwater evidence retrieval.
