Ok , bear with me, this my not come out right but I am trying ;-)
I think people (even some on this thread) are trying to find a reason for why this happened. A "justification": 'He was being bullied by Austin, he finally retaliated'. 'He was just sitting there to get out of the rain, then he was attacked by both twin brothers.' This was racist, a hate crime'.
All false narratives as far as we know, right?
But i think people just try to find the "why". Because it makes them feel safer. It makes them worry less about their kids' safety. I mean, if this was provoked and self defense, then it cannot happen to me, am I right? If it was self defense, it will not happen to MY kid, surely?
They bypass the fact that the killer brought a KNIFE to school, then onto the school bus, into the school event. All three locations where there should never be a weapon, and kids should be safe. Them trying to find a reason, is them trying to find a reason why this would NOT happen to them or their loved ones.
And then of course you have the opportunistic people who see they can rile up unrest, promote a false narrative to benefit their own goals and beliefs, their own agenda, and those wanting to get fame and make a quick buck on this situation (spokespersons, press conference, those people..) and try to make this into what it is not for their own benefit. I do not even think those people have KA's best interest at heart, to be honest.
anyway. MOO etc etc
