Question:
Why do some killers target schools?

Hypothesis:
They didn't have a particularly happy or supportive time while in school.

Solution:
Assess how people that are at-risk while in elementary school are supported. Mitigate the negative impacts they experience. Take ownership of their actions years hence by continuing to monitor and support them.

No, this doesn't solve every scenario. But, this is one scenario that can be called out and targeted with solutions.
