Mass shootings by kids are not the best example of this though. You can claim that the kids is shooting on those who pissed them off.

But seriously, that is not natural. You don't just kill your class mates. It does not make sense. You would tell mom and dad and when you tell them that you want to kill the other boy, they will change your school. Problem solved.

It smells of the act of brainwashing by those who benefit from broader population effects this results in. Like disarming the people. And distraction from a bad economic etc.

Fake terror/false flag events are basics of evil, corrupt, power abusing, power hungry elites.
