See my other comments on it - our sensibilities and emotions often tell us things that could be hazardous to the Constitution.
This is exactly how our enemies use our Constitution against us, because they take the concept and run it to the extreme. Free speech does not mean you can say whatever is on your mind, repeatedly, when those words lead to a death that was not one carried out by those who are legally sanctioned to carry out a death penalty. An example would be repeated calls for a known serial killer to receive the death penalty. That would be covered.
