Garland could be asked to resign, but if he declines to resign, they would have to impeach him.
If they went that way...I personally don't see Biden doing that, even though it would be shooting himself in the leg to leave Garland in office after he proved himself that incompetent.
SOMETIMES grand juries indict people, and sometimes they don't. NOTHING about this case is normal, sedition is not normal.
You cannot infer when there is no information being offered, you can only speculate.
Even indictments are no guarantee that there will be convictions. Juries have to hear these cases, and juries are made up of human beings, who are not known for being governed by logic. One magat on a jury is a hung jury, two magats on a jury is a disaster...The selection process for jurors, if there ever is one, will take weeks if not months, just for that one preliminary step...Both sides will be hyper particular, and will disallow as many of their opponents jurors as possible.
If indictments came out today, Most if not all of them wouldn't see the inside of a court room for the rest of this year, and possibly a good chunk of next.
