I read that there is a campaign in the United States by Civil Rights/BLM campaigners to arrest/charge Carolyn Bryant Donham, who lied in 1955 and claimed that she had been wolf-whistled at and grabbed on the wrist by Emmett Till, a Black teenager who was subsequently lynched by two men. At their trial, she testified that she had been sexually harassed by Till, and the men were acquitted. Donham admitted to lying in an interview with a journalist.
What I find hard to understand about this campaign is that, even if she did lie, it's hard to see how she can be legally held responsible for two men taking it upon themselves to then murder him in revenge. Can a person be held responsible if their lie leads to a murder? If I falsely claim that person A did something relatively minor and negative to me, and person B then murders person A to avenge me, am I really (legally) responsible for that?
Of course, I'm assuming that she could be theoretically tried for perjury, but I doubt that would carry a huge sentence for a comparatively minor crime committed while young. Or is there a special charge for making false claims which are likely to lead to malevolent acts by others? Presumably, living in a society which was extremely racially-polarised and where lynchings were commonplace, she would have known that if she lied, negative consequences could occur - is that a relevant fact?
