I wouldn't read too deeply into "timing" without a more comprehensive picture. Mass shootings are necessarily new, but it's a culture that has become increasingly prominent the past two decades.
I would prefer this discussion took a more constructive (and realistic, practical) turn towards discussing how to improve response time without suggesting a solution that clearly the military itself (and their security experts) do not deem acceptable, and just flat out isn't going to happen.
