Brian Cates, @drawandstrike, maintains that to this day.
I viewed Rosenstein as a white hat for awhile, even afer Mueller was appointed (I viewed Mueller as a black hat). After awhile, I forget exactly what Rosenstein did or said that flipped my point of view, I came to view Rosenstein as a black hat. I'm still "there."
To be fair, there are shades of gray. Comey is full-on black, but some of these snakes might come at least partly clean and the reveal progresses.
“I viewed Rosenstein as a white hat for awhile...”
If memory is correct, Rosenweasel wrote POTUS’ Comey-your-fired letter. Maybe that is why one could see him as a white hat in the beginning. But as things have unfolded .... That letter is either a stroke of genius by or luck for Trump. Rosenweasel can’t support prevaricator Comey if it comes to a criminal prosecution. Rosenweasel also sold-out his fellow conspirators by doing this, because Comey was part of the inner circle. If he refused to write the letter, he would have had to resigned or be dismissed. If he resigned, he would be out of the “action” and perhaps be subject to some type of “accident” that seems to happen to certain DC types when needed.
