I don't like either of them, and I can't remember what KH said about JM.
The only surprise about this is that it hasn't happened a lot sooner considering the way KH likes to give her opinion on everything.
That said, this must be horrible for her children and I feel quite sad for them, but I can''s work up much sympathy for KH herself.
JM's response does seem a little gloating. A simple comment saying it's a shame it came to this when an apology might have prevented it would have done.
