LMPD officer's wife dead from flu, remembered as giving, loving mother

Shooting back at a mass shooter is the least worst alternative.

The most likely scenario in a school executing a standard shelter in place plan is the shooter forces entry into a classroom with students laying close to the ground and a teacher inside. The least worst outcome is the teacher shoots the active shooter as he's coming through the fatal funnel (the door). The worst alternative is the shooter forces entry, and shoots as many students as their ammo allows.

Concealed carry for teachers is a much more reasonable option than simply letting them and their students die.
