Last month a serial killer was caught because his DNA partially matched a close relative, in this case his son. Is it fair to use a policing method that definitely will have a disparate impact on blacks? eg. there are proportionately more DNA fingerprints on file for blacks than for other groups, therefore it is likely that there will be proportionally more blacks identified by familial searches. Several years ago a serial killer was racially identified as predominantly black by DNA testing, which changed the direction of the search from a white man, and the perp was caught. Even though the racial profiling was a success the (black) police chief said that he wished the technology could be put back in the bottle. Is it fair to use DNA testing for ever increasing identification purposes or is it an invasion of privacy? It is a tough call.
