A Finnish study has identified two genes that are strongly linked to violent crime. Could this discovery be used to stop future acts of violence?

It seems not. The study of 900 Finnish criminals found less than 10% of violent crime can be attributed to these genes. Violence in society is clearly much more complex than a few differences in our DNA.

But the idea of using our genes to try and predict future behaviour is worrying. Presumably there are many individuals with these genes who lead law-abiding lives and never lay a finger on anyone.

The genes may be linked to the brain chemical dopamine.
