That is the question I don’t understand. From the reports I’ve read he crashed nearby and was outside with the rifle for about 10 minutes. I don’t believe for a second that wasn’t called in to police who should’ve immediately notified the schools in the area of what was going on. I read an article saying this particular school district has had something like 40 lockdowns this year because of border patrol pursuits/activity. It’s not like it was a foreign concept to them and they completely failed.
