... once you grant the power to these groups, then they become unaccountable, and they can get out of hand. That’s one of the ironies of power.

They’re not elected; they’re not authorized by any legislature. That’s what makes it so dangerous.
You could say this is what the courts did, through ineptitude, for the Bundys.
