Charles P. Pierce writing at Esquire:

There already is some talk about this event being a "random" one. But it is not. These things are becoming as regular as rain, as predictable as the summer heat. The only thing "random" about it is the shooter. He could be anyone, and that's the point. There are people who spend money making sure that he could be anyone, and there's nothing "random" about how they do that. There is nothing "random" about this country's ludicrous disinclination to regulate its firearms. There is nothing "random" about the millions of dollars that the NRA spends to convince people that they should have the right to carry their assault weapon anywhere they want to carry it, including into an airport terminal, if they so desire. There is nothing "random" about the politicians who truckle and bow to this lucrative monetization of bloody mayhem. These are all deliberate acts with predictable consequences.
