Telegraphing or outright warning them?
Telling them what will happen to them if they violently revolt could prevent the revolt.
Letting them know that they will not be protected by corrupt Governors, Mayors, DAs, and Judges makes them second guess if they want to participate.
It's called psyching them out.
Warfare 101.
It's exactly like what the shills try to do to anons all day every day here.
Except it works for POTUS because he is a winner.
And he can carry out his threats legally.
