The educational power structure is based on the idea that education is an unmitigated good that eliminates violence. When violent incidents occur in schools this creates cognitive dissonance for educational and leftist leaders. Instead of questioning their utopian thinking, they must find someone or something to blame....typically conservatives and the NRA. Logic flies out the window.... otherwise they would be forced to admit that their flawed thinking set up the conditions favoring violence by neutering the power of teachers to defend those in their care.
