What makes this ruling particularly troublesome is precisely what the Post chooses to omit from the article – that the banner in question was not actually ever on school grounds.
This is a disturbing precedent for student rights. The Supreme Court is basically saying that public schools can punish kids for exercising their right to free speech off of school grounds, where it can in no way interfere with the school’s ability to educate.
You had better believe that this is going to be held up by prosecuting attorneys as overruling Tinker in the future. That’s not just bad news for school papers – that’s bad news for pretty much anyone in a public school.
