Police in North Dakota borrowed a $154 million MQ-9 Predator B drone from the Department of Homeland Security to arrest a family of anti-government separatists who refused to return six cows that wandered onto their farm. After a standoff over the refusal to return the cows, local authorities called DHS and asked them to deploy a multi-million dollar drone to surveil the farmer’s property. This incident was the first time a drone owned by the U.S. government was used against civilians for local police work.
