Rapid DNA in action

This article reports early adoption of Rapid DNA technology in Bensalem, Pennsylvania and a few other sites around the country. The equipment requires little training and returns results in 90 minutes. Scientists are generally satisfied with the accuracy of matches from cheek swabs but consider crime scene DNA much more complicated to process and interpret. A current limitation is that most machines only link to local databases, not the FBI’s national CODIS system. Critics worry that the technology will tempt police to collect DNA from anyone they deem suspicious, leading to an ever-larger DNA database susceptible to misuse.
