Moore missed. A bystander named Oliver Sipple had grabbed her arm, and prevented a second shot as well.
It was a good deed that didn't go unpunished. As Lynne Duke wrote in the Washington Post in 2006, "... Oliver 'Billy' Sipple just happened to be standing in the path of history, right next to Sara Jane Moore, the would-be assassin, as she raised a .38 and aimed it at President Gerald R. Ford outside San Francisco's St. Francis Hotel.
"Sipple, a former Marine and Vietnam vet, saw the gun. He grabbed Moore's arm as she fired and saved a president's life. Afterward, he told people anybody would have done the same.
"Only later, after he was outed in the media as a gay man, after his parents back in Detroit were hounded and teased about their gay son -- only then would he realize the personal price to be paid....
"Oliver Sipple flew to Detroit to try to put his parents at ease, to explain 'that he wasn't embarrassing my father in any way, because he wasn't in the same state with him and he was an adult and should be able to live the way he wanted to.'
"The family became estranged... Oliver was not disowned, as some reports of that time said. But the family needed to absorb what had happened.
"Back in San Francisco, Oliver fought a battle on another front, against the media. He filed a $15 million lawsuit against seven newspapers, accusing them of invading his privacy."
After a few years, he lost his case. Oliver Sipple's unfortunate story is, of course, more complicated than these short excepts, involving lingering suffering from his time in Vietnam, a reported decision by Harvey Milk to publicize Sipple's orientation, heavy drinking, bad health and death in 1989.
