Think I agree with lexi, a lot of people barely under IC codes, and only a few do use them. Some people will just say white, mixed race etc when describing a suspect which I believe is equally acceptableWould be nice, but I think this would be best if it was up to the officer to use, rather than it being taught to everyone, or being required to use instead of the current one we use at the moment. It would be hard for a lot of people to remember these.
Especially with the lack of pin-point identification we're able to do on a suspect in the server, it would likely lead to mis-identification
