So Comey must be arrested.
He has revealed the identity of a minor who was a victim of a sexual attack, causing them considerable further distress due to an extremely large amount of media attention that was instantly predictable.
On that fact alone, he must be fired for gross misconduct, arrested and held criminally liable.
On top of that he has directly interfered with the election process. If done intentionally, this is illegal and so he must be prosecuted to determine the facts.
If done by accident, he is incompetent and must be fired for gross negligence.
Why is he still in post? He should be preparing his legal defence against these two charges while in jail or on bail.
