Sorry, there’s no question that leaving an external door open, for any reason, represents a security risk. It’s something that admittedly teachers have done for years, and 99% of the time there aren’t any negative repercussions. Sadly, in the day and age we live, propping doors open is something teachers just can’t do anymore.
Oh for heavens sake, NO ONE has said that. But who knows what happens if it takes him a couple more minutes to get in. Maybe the security guard comes back from the parking lot and spots him. Maybe a teacher spots him and alerts the main office sooner. Maybe the first 911 call comes in quicker. Maybe teachers have more time to secure their classrooms. Minutes are precious in this kind of situation and it’s nonsensical to say a possible delay would have had no impact.
And maybe you’re right and it wouldn’t have made any difference. We will never know. Just saying that a lot of things went wrong, and this was one of them.
Weren’t there 911 calls about 15 minutes before he even got to the school, when he crashed into the ditch & shot at people across the street?
