PASSAGE OF THE DAY: "Limited pilot studies have already raised concerns about the machines’ accuracy, including their failure to produce usable profiles, contamination of samples due to leaks in the machine, and the generation of at least one faulty profile. These machines are also being used by police in ways they aren’t intended for. They were designed to test samples taken from individuals for identification purposes, but local police departments are already deploying them on crime scene evidence, which is often far more complex. Such samples often include DNA that may be damaged or degraded, is present only in low amounts, or mixes many people’s genetic material. The FBI’s expert “Scientific Working Group on DNA Analysis” sternly warns that only a trained forensic DNA analyst can interpret crime-scene samples, and that Rapid DNA machines should not be used on them. The scientists also point out that “crime scene samples are often irreplaceable, and Rapid DNA instruments consume the entire sample.” The National District Attorney’s Association takes a similar position. But local police are not listening.Second, “cheap and easy to use” is a perfect recipe for overuse, particularly when it comes to sensitive technologies in the hands of the government. We have seen this dynamic with cell phone location tracking, face recognition, and communications eavesdropping: intrusive information collection that was once subject to “natural limits” because it was expensive gets deployed far too broadly when new technology makes it cheap. Rapid DNA machines are likely to have this effect. Our DNA is far more than a replacement for the fingerprint; it is the “nuclear weapon” of identifying technologies. It can reveal much more — and more intimate — information than simply our identity, including our propensity for certain diseases, our family members, and our ancestry. And, as technology develops, DNA may reveal even more. Third, Rapid DNA machines are likely to encourage the growth of government DNA databases, putting some of our most sensitive information in government hands. It also raises the likelihood of false hits. Even before Rapid DNA machines, we were seeing local police departments asking too many people — even kids — to provide DNA samples. This cheaper, faster technology — combined with the fact that many states have expanded their laws to authorize DNA collection from those who have merely been arrested — is only likely to exacerbate the problem."
