Keep in Mind a small measure of revenge was employed already. Comey was speaking at a law enforcement conference in LA (probably the keynote speaker), when he sees on TV backstage he’s been fired. He was humiliated in front of his peers. Further, he was informed that since he was no longer a US Gov employee, he had to arrange his own flight back to DC.
And Mrs Clinton should have been required to watch as Mr Comey was receiving his just deserts since there was complicity between the two.
