The detective should not be allowed to join a gang or be a gang leader

I looked into it and apparently detectives, like command, can't join gangs. But commqnd can be made gang leaders if it's low enough pop, so I think the same is true of detective.

Either you are mistaken about a detective gang member like they assumed the identity of a detective, or they were a bad detective pseudo joining a gang. I couldnt say.
