The First Amendment guarantees the right of protestors to say "Fuck you, pig! I hope you die, you worthless motherfucking murdering piece of shit racist!" It is hard for me to envision that this does not get struck down as unconstitutional. The authors tried to give it a fig leaf by saying the insults need to be such that they would have "a direct tendency to provoke a violent response from the perspective of a reasonable and prudent person" But that standard first fails for vagueness. And second, it fails because it is targeting a specific kind of speech that is directed at police officers.
