Badge of Deceit is a documentary programme that examines actual criminal cases and the methods police use to resolve them. Structured as an episode within a larger series, it steers clear of fictional storytelling and instead presents real‑world investigations in a straightforward manner. The focus is consistently on how detectives piece together evidence to bring perpetrators to justice, offering viewers a clear view of the investigative process. In this particular episode, the spotlight falls on geographical profiling as the central investigative technique. Investigators apply this specialised approach to track down a serial rapist, using the spatial distribution of offences to narrow down the suspect’s likely area of operation. By mapping where attacks have occurred and analysing patterns in the locations, the team is able to move closer to identifying the perpetrator, demonstrating the practical power of location‑based analysis. The segment walks the audience through each stage of the profiling process, from the initial collection of crime‑scene data to the creation of a geographic model that highlights probable zones of residence. It shows how the combination of forensic findings and spatial reasoning guides police resources, ultimately tightening the net around the offender. The episode underscores how geographical profiling can be a decisive tool in solving serial offences.
