These shootings. I think we need J G Ballard back. Looking back through previous such apparently random events, we might observe that:
• The perpetrators are almost always white.
• They are almost always lower middle class or middle class.
• The areas in which the shootings take place are almost always comfortable, although not luxurious, suburbs, a good distance from the local metropolis. In demographic terms they tend to have a rather lower racial mix than is average for the state.
• The median income is always bang on average for the state. They tend to be places with otherwise low crime figures.
I don’t really know what this tells us.
