I’ve not read this entire thread and this may have been discussed but I have two questions.
First aren’t most if not all classrooms required to have windows for fire escape? This of course would have been another point of entry. Maybe not there? Maybe the windows were utilized?

Second where does an 18 year old get enough experience with two newly purchased rifles and ammo to accurately hold off LEO as long as he did?

The lord took home another choir of Angels. God bless them all.
