Yet many are uneasy about the use in courts of law - and in matters of life and death - of basic science that is only just creeping out of the lab.

Neuroscience is being used by serious scientists in real labs, but the people trying to apply it in courts are not those same people."
Seena Fazel, a clinical senior lecturer in forensic psychiatry at Oxford University, says he's uncomfortable with the long-term implications and wonders . . .
