In the media coverage of the Newtown massacre, there's an understandable focus on the number of children killed. As there should be. There's not enough focus on how this is yet another attack by the decentralized network of spree killers with a disproportionate number of female casualties, but that's for another day. The above picture is of Christine Greene, who was murdered aged 9. A neighbour had taken her to see a public meeting of Arizona Congresswoman Gabrielle Giffords when the event was attacked by Jared Loughner. Just a reminder that we've had child victims of the spree killer network -- and its support infrastructure -- before last Friday.
