Because he doesn't have to waste political capital on a has-been scumbag like Klink. The law will catch up with him sooner or later, either in the form of his very-own appointed Mary Jo White, or the Devil himself. Or somewhere in between. I wouldn't be surprised to see him arrested for something shady, sleazy or down right murderous SINCE he's been President. Don't worry, Clinton will rot in Hell in the worst possible way, and he's already secretly worrying about it. Best let him stew.
I agree with you that Bill Clinton cannot escape the hell for which he is bound - unless a true miracle took place - which I do not expect. There are too many dead bodies.
But Hillary Clinton is another matter. She still has the full intention to do a Marxist make-over of this nation.
The thing that will bring the remarks from future historians will not be that Bill Clinton escaped unimprisoned - but that Hellary Clinton did....much to the demise and destruction of our country and thousands if not millions of human beings.
