Why can't they publish wanted people's skin color's?

I don't understand this... when a news outlet reports on a crime and they post the description of the people they list everything they are wearing and all but their skin color! Every time! Like it would help if they were black, Hispanics or white. But in all respect they are usually black people 90 % of the time and when I view the video feed of the crime it's no surprise they are black people so what's the deal why can't these news outlets just post their skin color? It would help the public a lot if they knew... Yet I wonder why are the majority of crimes on the news 90% of the time comited by black people?
