What stronger proof is needed?
Here is the absolute, BEST part of this whole thing. In dissent Ginsburg wrote, “But they had no vested right to promotion.”
So, working for the city for many years (putting their lives on the line DAILY), studying, testing and passing is not a “vested right” to a promotion if you are white.
BUT, those same things, along with black skin DOES give you a vested right? Gotta love that thought-process!
