Agreed in an ideal world we would address lightening strikes (the bigger risk) first by investing in more lightening rods, then once that problem is under control we should work on reducing the even less common school shootings that occur....
Or we should just fix the very **common** real underlying issue, the lack of access to mental health and education, that way we can fix not just the problem with shootings, but the much more common and overall problem of violence and lunacy among the populace.
