The Sheriff has announced that there was an armed officer on the campus at the time who never encountered the shooter.
Hmmmm.
Even if the campus is 45 acres, the shooter fired 150 rounds, shot 3 people in the parking lot before entering the school.
What did the officer do?
One armed officer at a school with 3500 students from the looks of it that campus is HUGE has to be in order to hold that amount of students. You need an armed guard at every single entrance to the school
It takes several defensive shooters. I suspect the poor guard had a glock 19 . The campuses out here that have trained coaches and ex military and have ar15s in a central safe as well as accessible pistols. They also have communications head sets they practice with for coordination and triangulation of targets. after training they practice on site 1 time a month on Saturday. They work on multiple shooters as well single shooters. They have both tactical defensive plans as well as offensive . The idea is to set defensive lines while police and sheriff units arrive with real swat guys. They have to shoot 100 rounds per quarter at 15. 25 and 50 feet. The AR15 crew has additional practice requirements. We will see metal detectors in schools very soon. Nothing is perfect but something is better than nothing. The answer is not to take our guns.
