I think you're absolutely right. Mueller needs to be held accountable for everything that happened under his watch. He was just the figurehead, but he allowed all this stuff to go on under his nose, and whether he knew about it, or not, the fact that it went on shows he was complicit, because he appointed these people...and put his signature on the paperwork that approved it all. Even the final report...that he didn't even write has his signature on it. Let the chips fall where they may. I don't care if he is an old fart. He still played a part in it all, and got paid well for his services. I'd still like to know how many times he and Comey communicated during the whole investigation. We know Comey met with him just after he was named as Special Counsel. What did they talk about, and how many more conversations did they have over those years, and how much did Comey's input influence the investigation?
Put Mewler in the General Population amongst a bunch of MS-13 and other gang-bangers.
Or...something even worse.
Hanging is too good for him, given his past.
