Workplace racism at major tech company

I worked for a MAJOR tech company and transferred to a new group. The new manager could not stand that I, a brown guy, is the go to guy. All the time she would ask who is helping me, where did I find the information, who double checked that my work is correct, and a million other questions that she doesn’t ask my white colleagues. Anyway, one day, a white co-worker explicitly discriminated against me. Other colleagues saw it and became quiet. They have bills to pay too. But they are also white. I complained but got retaliated against (smaller bonus, no raise). When I asked for HR to become involved, I got fired.
Most of this is documented. However, the all white management decided to hire the largest (well among the largest) law firm to fight on their behalf. The story is yet to be concluded ……
