The elite has complete control over the investigatory and prosecution arms of the state. Barring a revolution, nothing is going to happen.
Look at the Weiner laptop with Hillary, Epstein, proof that the DOJ and FBI launched an illegal coup attempt against Trump, the Hunter laptop, the stolen election, etc.
It's already quite clear that the political and economic elites are unbelievably corrupt and have completely captured our "democracies." There's not a damn thing we can do about it.
There is, but its going to be a slog. And I'd argue that slog has already started.
The 'arrest Trump' gambit I see as desperation. An organization confident of its position doesn't do that. And it makes him a martyr, not to mention signaling that the old rules of civilized society don't apply.
I'd argue it is cutting off the head of the hydra. Not so sure there is a foolproof plan for that, no matter how much scheming goes on.
That's why they turned up the heat slowly, hoping people wouldn't be too quick to anger. Incremental, one step at a time.
