English furor: “Gary Pugh, the director of forensic sciences for the British police has sparked controversy after he suggested that children as young as five who display ‘future offending traits’ should be placed on a DNA database so they are more likely to be picked up if they commit crime in the future.

Pugh is almost certainly talking about children who have what are known as ‘callous-unemotional’ traits, described somewhat less politically correctly as ‘kiddie psychopathy’.

These have indeed been found to weakly predict future antisocial behaviour, but the picture is more complex than it seems and, as we’ll see, they aren’t a good basis on which to base future crime fighting efforts.” (Mind Hacks)
