Rothstein continues to recognize that the line between
de facto and
de jure discrimination is fine and even debatable, but he considers police support for white supremacist mobs a clear example of
de jure discrimination because it constitutes the state government’s failure to equally protect all groups under the law. Again, the crucial distinction is the difference between isolated acts of discrimination (say, by an individual police officer) and a clear, pervasive pattern of discrimination by the police department as a whole—in other words, the
institution of the police supported the mob, which represents official policy, as opposed to an individual police officer doing so out of private feelings. It is also important to remember that, if discrimination is
de facto, this does not make it any less unjust or harmful—it only changes the kind of role the government should take towards resolving it.
