It depends on the crime. But for crimes like, say, sexual assault being male is indeed a huge factor in likelihood to offend. Disparities between rates of women committing sexual assault and rates of men is immense - one or two orders of magnitude depending on the exact crimes counted.

I agree that an AI shouldn't use race or gender as an input. But we should not surprised when AIs have disparities when predicting risk of committing crimes, when there are disparities in the rates of actually committing crimes.
