A Greer County undersheriff suspected of impaired driving refuses to stop for a Mangum Police officer, drives home, and begins drinking alcohol while the traffic stop is still unfolding. Moments later, the county sheriff arrives, turning an already unusual DUI investigation into one of the most controversial law enforcement encounters captured on bodycam. This educational case study examines the publicly released bodycam footage involving former Greer County Undersheriff Amber Espinosa and Sheriff Steve McMahan. The video analyzes the officer’s response, the legal and tactical challenges created during the investigation, the impact of post-stop alcohol consumption on a DUI investigation, supervisory involvement in an active criminal investigation, and the events that ultimately led to Espinosa’s resignation and criminal charges. This case study examines the incident using publicly released police bodycam footage, dashcam video, surveillance footage, cellphone video, 911 calls, dispatch audio, witness recordings, and investigative findings, when available. Analysis and commentary are provided from the perspective of a former federal agent, former law enforcement officer, and digital forensics examiner. Whether you are an aspiring law enforcement officer, a current officer, criminal justice student, attorney, first responder, or simply interested in public safety, these case studies are designed to highlight tactical decision making, officer safety principles, legal considerations, and practical lessons that can be applied to real-world law enforcement encounters. ⚠️ VIEWER DISCRETION ADVISED ⚠️ This video contains real police bodycam footage from a critical incident that some viewers may find disturbing.
