Like Taking DNA from a Baby


British police have almost 3 million DNA profiles, about 6 percent of its population, on file. But that's not enough Dave Johnston, the head of the Metropolitan Police's Homicide and Serious Crimes unit. He wants DNA samples taken from all babies. "We have 300,000 unsolved cases where we have taken a profile at a crime scene but have not yet matched it," he said. Johnston did not say how many babies he suspects may have committed those crimes.
