The post? An Instagram detailing her experience with covid. The sheriff claimed that the post was "scaring" parents, and threatened the _*teenager_* and her parents with arrest if it were not removed.
Her parents sued, and just yesterday the judge ruled in their favor. Saying that the police and school district (which attacked the teens reputation in the media shortly after the incident took place) violated her 1st amendment rights.
That, my friends, is a freedom of speech violation. It's not when a private company deletes your tweet, it's when a government official threatens your freedoms if you don't comply.
