Eugene Volokh comments on a case that raises an issue I’ve discussed here occasionally – can one person’s right to privacy trump another person’s right to talk about their own life:
Greg A. Fultz put up a billboard showing himself holding what appears to be empty space, with the words “This Would Have Been A Picture Of My 2-month Old Baby If The Mother Had Decided To Not KILL Our Child!” and some endorsements (apparently later removed) from pro-life groups, including the words “PRO LIFE” and “RIGHT TO LIFE.” The billboard didn’t identify the man’s ex-girlfriend, but presumably some people who knew him and her would figure it out.
Read more about the case and issue on The Volokh Conspiracy, where Eugene also cites some case law relevant to the issue.
