"In the summer of 2002, the FBI, the Baton Rouge Police Department, and several
other agencies began a massive search for a serial killer suspected of murdering
three women. Based on an FBI profile and an eyewitness report, they upended
southern Louisiana looking for a white man who drives a white pickup, collecting
DNA from more than 1,000 Caucasian males. They found nothing. Meanwhile, the
killer struck again.In March 2003, investigators turned to Tony Frudakis, a
molecular biologist who said he could determine the suspect’s race by analyzing
his DNA. Uncertain about the science, the police asked Frudakis to take a blind
test: They sent him DNA swabs from 20 people to see if he could identify their
races. He nailed every one.On a conference call a few weeks later, Frudakis
reported his results on their killer. “Your guy could be African-American or
Afro-Caribbean, but there is no chance that this is a Caucasian.” There was a
prolonged silence, followed by a flurry of questions. They all came down to
this: Would Frudakis bet his life on his results? Absolutely."
Depending on how it is used, this seems like a fair and a good way to focus on a suspect. It could mean that if you have a number of suspects, some white and some black - you could focus on the black ones. What it shouldn't be used for, is to target all black males, just because they are black and male.
