A former high school student has lost his case in what is the US Supreme Court's first major ruling on students' free speech rights in almost 20 years.

This is a terrible decision.

1) The student was not on school property at the time.
2) The banner "Bong Hits 4 Jesus" is obviously humor.
3) The students property was destroyed with no compensation.
4) The decision is based on the fact that illegal drug use is illegal by definition, and therefore promotion of such is not protected speech.

So, what if the banner had read "I support Medical Marijuana" instead? What if it said "I support late term abortions" and was displayed off-campus at a planned parenthood rally - would that also be speech the school can legally suppress?

According to the Supreme Court, in a word, yes.

These are your right folks, slipping away...
