I sometimes worked with an inter-agency narcotics task force. One of the guys, who worked the far end of the county and thus wasn't around a lot, was a state trooper and had a Malinois patrol dog that always seemed to be at Defcon 5 alert level. One day a bunch of us were sitting on the floor of the squad room when they walked in. Dog walked toward me, eyeing me like I was a steak. Handler leaned down and whispered to the dog, "Friend." Whereupon the dog came over, gave me a big wet kiss on the face and rolled onto his back for a tummy rub.
