First Amendment Protects military funeral protests, Supreme Court says.
Pretty strong defense of the Marketplace of Ideas from Chief Justice John Roberts:
Speech is powerful. It can stir people to action, move them to tears of both joy and sorrow, and — as it did here — inflict great pain. On the facts before us, we cannot react to that pain by punishing the speaker. As a nation we have chosen a different course — to protect even hurtful speech on public issues to ensure that we do not stifle public debate.
From the lone dissenter, Samuel Alito:
Our profound national commitment to free and open debate is not a license for the vicious verbal assault that occurred in this case.
