Well, it's quite clear that the LAPD suspected him of being a racist.

I just told you that he's had a history of making racist remarks to black people. What else do you want.

In an interview done sometime later, way after the OJ trial, and on TV, Ferman later admitted that he used the N-word and that he made some very bad moves as a detective. He cut corners and "busted heads" to get results.

And what question do you want me to answer so badly?
