Stzork was a cop with an agenda, he ended up being (properly) fired for it. The man despised Trump, and promised his mistress that Trump would never be elected. This is the same guy and mistress that discussed going easy on Hillary when he was investigating her.
Or, the simplest explanation is that a guy with decade+ experience investigating graft, corruption, and mobsters actually has a real history and knowledge of Trump, that certainly is of no consequence to you, and has a far, far, far more informed opinion of a person like Trump than any of us do. This would have all been targeted before the Orange Sponge ever considered running for president. ....why then, would this informed history of investigation suddenly change things about the near-certainty of his criminal history?
I don't know why you guys seriously go out of your ways to convince yourselves via arguments that you never would have supported a mere 5 years ago. It's like the entire history of law enforcement, investigation, and justice just suddenly doesn't matter for this specific issue, for some undisclosed reason.
You are literally arguing for the expungement of essentially the entire history of federal prosecutions because you suddenly believe in some newly-established "bias against criminals doing criminal things" violation that never existed.
