Question for the dissenters- why? What's your constitutional rationale?
The Framers' intent has obviously never been to protect all forms of speech. Categories of speech have always been held as deserving varying degrees of constitutional protection, and governmental restrictions on time, place and manner of expressions have been deemed legitimate in many cases. It's not really a stretch to consider than in these circumstances, the manner of the speech (violent, unwarranted insults) and its time and place (a person's funeral) are circumstances exceptional enough to warrant restrictions.
