Re: Why wasn't Worf in Code of Honor?
The script apparently designated only 2 guards as black, and the original director went from there. I think there was also mention of behavior that LeVar Burton and some other actors took offense at. I think the guards bit is mentioned at Memory Alpha, but not sure where I read the stuff about Burton.
