Praising a murderer for committing a murder is not incitement and is protected speech. Under Brandenburg v. Ohio (1969), speech loses protection only if it is directed at inciting or producing imminent lawless action and is likely to produce it. A comment on a murder after the fact can’t meet this standard unless the comment is “go do another murder right now!”

Kimmel also did not praise the murderer. He implied (incorrectly as it turns out) that the killer was right-wing.

Your misstatements of the well-known facts and law in this case cast doubt on the effort you put into researching the other issues mentioned.
