You have to understand, some of those rogue agents might go into a “bunker mentality”, and be uncommonly hard to dislodge. It may take several sweeps to root out all the subterranean rot.
And make the retribution, when it is served, mandatory and final, so some future Democrat regime cannot simply reinstate them.
You’re right, of course. Reforming a long-standing, entrenched bureaucracy such as the FBI is a monumental task. But I think Kash and Bongino understand this. It won’t be quick or easy, but, at long last, we are on the right path.
