I suggest you all to review your American history because things like this have happened in several occasions and to several degrees.
You should know that Tammany Hall was a thing, and so was the Business Plot, and the Kent State shootings and things like the Battle of Blair Mountain were more common than you would believe.
I understand that to young people, seeing what's happening is scary, but democracy is a continuous battle that we tend to forget it exists but that we ought to fight as the alternative is always worse than anything you might imagine (based on the testimonials of survivors).
EDIT: I added few links with worth reading articles.
