How does naming the ethnicity of a group of criminals help in solving or preventing the crimes the commit? If there's a clear, proven answer to that, one that works obviously better than other methods to solve or prevent it, then by all means: name this parameter. In all other cases, it helps nothing. If anything, its counterproductive. Let me give an example: a significant portion of Dutch heavy criminals, in the niche of harddrug trafficking were raised in poverty (relatively, its still the netherlands), in tough neighborhoods, by parents/families that often fall partly outside of the established social constructs. If you look carefully, non of these parameters are "of certain ethnicity", but the enthnic group underlies many of these parameters. A populist politician, or racist, would say "they are all Marroccan". Which, except for the absolutists "all" is true, even. But it doesn't help one bit in preventing this crime, catching the criminals or preventing new kids to become the next generation. What helps is finding the traits that do lead to them turning criminal; many of these traits may stem from their ethnic background. Mind you: these traits are by no means excuses, merely traits that allow a clearer and more effective treatment of the societal illness that these criminals are.
