Ken Klippenstein is a very reliable journalist and this version of the manifesto contains the snippets that have been released by law enforcement. Also, considering the thing was hand-written, that very long version involving his mom is dubious. (And there’s not any good evidence that his mom is in anything besides decent/good health)
The author here knows what they're talking about, and while not explicitly saying it, they're saying there will be more Luigi's, Adjusters, whatever attention grabbing description you like.
More business execs will be recognized as the tyrants they are, and shot. Because the entire world just taught all the school shooter types that shooting a business exec will turn you into a folk hero. It will get you fame and admiration. It will get people trying to send you money for your legal defense. It will get you people spreading the word about jury nullification to use the system against itself.
This month taught would be school shooters to instead go for board members, ceos, and billionaires. And it's a far better lesson.
Unfortunately school shooters want to hurt society
Some of them, sure, but not all of them. Some of them just want a "high score", some of them just want to hurt somebody, some of them just want their name in the history books.
they aren’t interested in fame. They want notoriety.
It doesn't matter what you call it. They want attention, and they've been shown new way to get a shit load of attention, much of it positive.
I expect school shootings to continue to happen at the same rate, where we might see someone have a crack at a single CEO or Director in the next year.
It doesn't matter what you call it.
It does because it speaks directly to the motivation for the act.
