I just meant that it is unfortunate because since the shooter is dead, the questions we ask towards the authorities are now different since we can't seek answers from him.
So instead of "How can this be prevented in the future?", the question has become, "What did local authorities fail to do that allowed this to happen?" Regardless, both need to be answered. But in everyone's heightened emotional state, we want the answer to the second question to lead us to the answer of the first. I think that's the incorrect order, and one that deflects blame from the shooter to Virginia Tech.
Honestly, if the shooter were still alive, I don't think we have this discussion.
