Let's say he's wrong - as I firmly believe he is.
It's grossly insensitive to the parents. Vulgar. Cruel.
But saying cruel and insensitive things, to the best of my understanding - is not a crime. It's seriously bad taste. There ARE things you can do and say where you can be held accountable for the consequences. If you say something to deliberately provoke people - you won't have a case to stand on if you try to take people to court for kicking your ass. Go into a redneck bar and call them all a buncha queers - and when they bring your battered body into the courtroom, the judge will say, sorry moron.
Fire in a crowded theater. Slander and libel. Yes, you can be held accountable for damages you create.
Laughing at mourners at a funeral - isn't a crime. Maybe it ought to be, because it's revolting. But it isn't.
If someone harasses or makes death threats at someone - THEY OUGHT TO BE TAKEN to court. But the guy who gave them the idea - no one forced them to harass or threaten. You're on the hook for your own criminal behavior. You're not getting mileage out of "he made me do it".
Then there's the billion dollars. When whole corporations have to pay damages - you hear 10 million, 50 million, 100 million. When was the last time you heard of an INDIVIDUAL having to pay a BILLION? What damages could be worth that?
This is a dumb case.
