Every one of us wants to know that there was something we could have done, if we had been in this accident, to have prevented most of those deaths. We want to know that our tiny baby wouldn't have died, that our 3 and 5 year olds would still have their parents and their grandparents and their friends and relatives. We want to believe that our car is better, our car seat use is better, our driving is better, our luck is better.
We want to believe all that, because not believing it is terrifying.
But sometimes, none of that matters.
