The COMPAS analysis they refer to is exactly one of those cases where there is no bias whatsoever and they're trying to force the algorithm to conform to PC instead of reality. What the ProPublica analysis showed was that a black person and a white person with the same risk score have the same probability of recidivism. There is no racial bias. Black people have higher rates of recidivism, which means that they will also have a higher rate of false positives. This is mathematically unavoidable. I recommend creating a toy example in excel and playing around with some numbers to get an intuition for it.
