Light sentence for ‘bad’ genes

Monday, November 2nd, 2009

An Italian court has cut the sentence given to a convicted murderer by a year because he has genes linked to violent behaviour. Is the decision based on sound science and what are the implications of this precedent when we really do understand how our genome influences behaviour?
