Technically that was a calculated movement of it’s time. They wanted a black character in a role that spoke to an easy childhood concept of authority to imply that power dynamically having black people in a dominant respected role in social spaces is a normal thing one doesn’t need to get upset over. Hence the whole friendly cop thing.

They were aware through the gay black actor they had in the role that police was something minority communities had issues with but the hope at the time was that more diversity in the force would be a solve. It’s naive from a modern standpoint but they did try.

It was sad that they purposefully kept the gay part of the actor’s identity under wraps. They knew they were asking him to do something harmful by keeping his private life strictly secret but the actor agreed that he was doing something he deemed worth the sacrifice.
