Well... that was in the article, and part of what I was saying.
The 90% that were black were his customers because they were facing criminal charges. So... 100% of the blacks he has come into contact with through his job are alleged criminals.
That is what he based his comment on. Which would give one a very biased opinion of 'blacks'. Is this not true ?
I think it would give a reasonable view of Black 'criminal types'.
He also gave his view, which also seemed reasonable, of Asian and White 'criminal types', and it was against those types that he compared the Blacks.
