Here we go again. In our outrage over the Aurora massacre, we slip back into our habit of trying to make sense of the senseless, to trace a chain of causation back to its source, and eliminate that source so it will never happen again.

This fallacy reached its peak of absurdity after the Tucson massacre, when we as a society decided to stop using violent metaphors for about 10 minutes, because we all know Jared Lee Loughner wouldn’t have gone wacko if people didn’t say things like “let’s target” a congressional district. Then we saw Loughner’s loony picture, and all discussion about whether he was nuts ended.

Unfortunately, Columbine/Virginia Tech/Fort Hood/Tucson/Aurora will happen again, and again, because not every problem has a solution.
