These school shooting imo were a generation in the making and will most likely take a generation to solve. You have a generation growing up on mind altering drugs, told that they special and have the right not to be offended.
Then you throw some racest, self loathing, hate filled leftist teachers poisoning their minds. And when reality of the real world hits them they snap.
There are of course some other factors involved.
And of there are some that are out right false flag events.
It will take a while to fix this, but americans want a quick fix to everything.
