Gary Hesterberg was in a national park in San Francisco with his two lap dogs. A park ranger saw him with his dogs and told him that the dogs must be leashed. She asked for his name and told him to not to leave. When he started walking away, she shot him in the back with her "electric-shock weapon."
Rancho Corral de Tierra has long been an off-leash walking spot for local dog owners. In December, the area became part of the national park system, which requires that all dogs be on a leash, Levitt said.
The ranger was trying to educate residents of the rule, Park Service spokesman Howard Levitt said.
