How did THAT get there - the new DNA challenge?
Current technologies, even the ‘standard’ profiling method, are capable of detecting picograms (pg = 0.000000000001g) of DNA; that’s about the equivalent of a millionth of a grain of salt.

Three killers have been convicted this month of appalling crimes. Two were implicated through DNA profiling. The aftermath has seen renewed calls for both a universal DNA database and the death penalty, bolstered by a belief that advances in scientific evidence would eliminate the risk of wrongful convictions. Keeping everyone's DNA profile in the universal database could make a significant impact on the investigation of crime. But there are also cogent reasons why it would increase the risk of convicting innocent people. (2008)
