This is utterly insane. The court explicitly refused to consider context, saying that the remark, on its own, with no context, was inherently threatening and would have been regarded so by anyone with intelligence.
Woe betide you should you ever say anything taken out of context.
Find someone you really don't like, find a comment they make, interpret it as a threat, and file a complaint under anti-terrorism legislation.
Insanity.
