In a stroke of forward-planning genius, Gary Pugh (Britain's most senior police forensics expert), has come up with a way to address "future crime".... "Primary school children should be eligible for the DNA database if they exhibit behaviour indicating they may become criminals in later life, according to Britain's most senior police forensics expert." "'If we have a primary means of identifying people before they offend, then in the long-term the benefits of targeting younger people are extremely large,' said Pugh." "...it is possible to identify future offending traits in children as young as five" TARGETING YOUNGER PEOPLE...AS YOUNG AS 5...BEFORE THEY OFFEND.
