Hubby sadly had to use his rifle at work. A cow got loose along the interstate. She had already gotten onto the travel lane before hubby arrived, but ran back onto the shoulder. Hubby, several other cops, and an ag officer tried to corral her away from the road for darting. As the ag officer tried to get a clear shot, she spooked and ran back for the road. Hubby put her down with several bullets to the head. He felt bad about it, but knew it was better than the cow causing a pileup on the highway which would have had the same outcome with the possibility of human fatalities as well.
It happens more often than a suburban girl like myself ever imagined. We have vast expanses of rangeland here, much of it along roads and highways. Hubby hates loose cow/horse calls. The animals are often scared and unpredictable and there is always the possibility of being charged at or kicked.
