Profiling Children for Future Crime

My first thought when I read this article concerning a proposal in Britain to collect DNA from children as young as 5 years of age who may later be a criminal, was of the Tom Cruise movie where people were being arrested for "pre-crimes." Understanding that some young troublemakers have become U.S. presidents, sports heroes, bank presidents, and have held other high level positions in society, a plan to identify children for future crime seem utterly absurd.
