Identifying a suspect by his/her racial appearance is helpful if he/she still needs to be apprehended. But whether you can trust any broad category of human would probably be more reflective of their culture. As an example, if being an excellent con man is considered respectable in a given Central Asian country or area, we should probably be aware of that.
Sometimes you cannot identify them by appearance. I know Turks who looked anything but Muslims. I also know some Moroccan who looked to me like Spanish. You actually have to look at their names. That is, if you know their real names.
