Thanks for the map.
Criminals are deterred by NOT knowing exactly who is armed among the people they intend to victimize. At Columbine, the killers knew Gardner’s whereabouts by knowing whether his security car was in the lot in its usual place, or not, and could time their attack when he was gone, as I believe they did.
But they also knew to expect him back and to prepare to ambush him, which they did. Just knowing he was coming back armed diverted their attention at least partially from killing students.
What if the killers didn’t know how many administrative staff in the school were also carrying? What if it could have been quite a few, in addition to the visible deputy?
