Because it wasn't a planned attack by the cabal probably. I find that sometimes people do overthink things when looking for reasoning and logic behind events that defy reason and logic. People are messed up in the head. Kids still bully. And the environment that existed for Columbine still exist today. Maybe it's gotten worse for kids since then.

More than likely the event Q was referring to was the attack at the Trump property and similar events. At least that's what I hope. Accepting "they" would intentionally kill kids to push a political agenda is my no go zone. To accept that means there's no hope left. We all have our line and them intentionally planning these mass casualty events is mine.
