The Times did a good piece this weekend on the families of murderers and how they so often live in the shame of their loved ones. I thought the video, below, which looks at the family of convicted killer Ronnie Lee Gardner, was most affecting at showing how easy it is to cross the line into criminality once violence and abuse becomes part of a family's culture. 

By the end of the video, you see the children grappling with their own issues around violence, and their own encounters with the police, and the haunting sense that there is, perhaps, something in their blood.
