I suspect Stone is eating all this up as for whatever reason he likes this kind of attention.
He does like this adverse drama but I don't think it was right having CNN filming there and his wife so treated so disgustingly.
I think Mueller is treating Stone and Manafort so badly because they both have been close associates of Trump for decades. He's after Trump but these guys may be as close as he gets to him.
Stone will fight back. He's not the kind to roll-over. But he does have a family and his wealth to worry about, just like Manafort. Mueller is out to destroy them because he knows he doesn't have anything on Trump.
His ulterior agenda has been to drag this nonexistent Russian collusion investigation out for as long as he can so the powers to be can cover the tracks of the real bad guys in this country, Hillary and her rapist husband. And his own involvement into giving the Russians our uranium.
My hope is that in the long run, Mueller and his team of gestapo jack-boots get the same treatment down the road themselves. Just desserts.
