Ranger Uses Stun Gun on Man Walking Dogs off-Leash A park ranger used a stun gun on a Northern California man who was stopped for walking his two small dogs without a leash. The San Francisco Chronicle (http://bit.ly/yrsKc7) reports Gary Hesterberg didn't have identification and gave a phony name when he was stopped Sunday afternoon. He was walking two dogs off leash at Rancho Corral de Tierra near Montara, a coastal town south of San Francisco. A Park Service spokesman says the ranger, whose name is being withheld, used her stun gun on Hesterberg because he was leaving the scene despite orders to stay. San Mateo County sheriff's deputies arrested Hesterberg and he was booked for investigation of failing to obey a lawful order.
