I would imagine they actually have free reign, period. They could detain any minority they want, treat them like dirt, destroy their documentation if necessary so they can be deported. Trump DOES NOT CARE. He is exactly the Hitler-like type of person who could easily move on to “making people disappear” or ordering innocent people killed outright, possibly in massive numbers. He’s not interested in a perfect race, like Hitler was, but he is interested in isolating himself from exposure to anything and anyone that offends his delicate sensibilities.
