An FBI profiler is a specialized agent within the Federal Bureau of Investigation who analyzes criminal behavior to help solve cases. They study patterns in crimes, focusing on the psychological aspects of offenders. By understanding the motivations and characteristics of criminals, profilers can create profiles that assist law enforcement in identifying and apprehending suspects. Profilers often work on serious cases, such as homicides or sexual assaults, where understanding the perpetrator's mindset is crucial. They collaborate with detectives and other experts, using their insights to guide investigations and provide valuable information that can lead to arrests and convictions.
