Barry Cooper spent years as a Texas narcotics officer building drug cases before switching sides to teach civilians how to avoid the tactics he once used. Across seven chapters he breaks down how K9 units actually detect narcotics, debunks common myths about masking odors, and explains how handlers manipulate dogs into false alerts. He walks through the vehicle compartments officers check first, then details how a routine stop escalates into a legal search, covering reasonable suspicion, probable cause, and consent. A chapter on profiling has Cooper driving real roads, pointing out out-of-state plates, bumper stickers, and driving behavior that flag a car for interdiction officers. The series includes actual dashboard camera footage from real traffic stops, with Cooper narrating what each driver did wrong and what the officer was actually looking for. A closing chapter covers what to do after an arrest, from staying silent to handling recorded conversations in a patrol car or jail cell.
