She’s out. Sara, now 77, was one of the two women who tried to shoot President Ford on separate occasions in September 1975.
Moore tried it on September 22, 1975; Squeaky Fromme tried it earlier on September 5. Fromme, a Charles Manson devotee (unlike Moore, who had her own reasons), is still in prison.
Moore’s shot missed Ford of course. A bystander saw her and actually pulled her arm before she shot, but she managed to squeeze off a single bullet.
Here’s video of Sara Jane’s failed attempt:
