It is absolutely impossible for anyone to stay tuned to nothing but possible threats in their environment, think of everything, do everything right, and stay totally alert 24/7/365. They can't do it even in war zones, let alone in schools with a much lower perceived threat to personal life and limb.
On the other hand, successful offense requires only one single opportunity.
There will be mass shootings as long as there are people willing to commit mass shootings. The issue is reducing motive as well as opportunity for those.
