Journalist and self-proclaimed Freedom of Information Act nerd Ken Klippenstein claims to have released Mangione’s manifesto. He also believes that some news sources are withholding it.
Manifesto (source: Klippenstein)
To the Feds, I’ll keep this short, because I do respect what you do for our country. To save you a lengthy investigation, I state plainly that I wasn’t working with anyone. This was fairly trivial: some elementary social engineering, basic CAD, a lot of patience. The spiral notebook, if present, has some straggling notes and To Do lists that illuminate the gist of it. My tech is pretty locked down because I work in engineering so probably not much info there. I do apologize for any strife of traumas but it had to be done. Frankly, these parasites simply had it coming. A reminder: the US has the #1 most expensive healthcare system in the world, yet we rank roughly #42 in life expectancy. United is the [indecipherable] largest company in the US by market cap, behind only Apple, Google, Walmart. It has grown and grown, but as our life expectancy? No the reality is, these [indecipherable] have simply gotten too powerful, and they continue to abuse our country for immense profit because the American public has allwed them to get away with it. Obviously the problem is more complex, but I do not have space, and frankly I do not pretend to be the most qualified person to lay out the full argument. But many have illuminated the corruption and greed (e.g.: Rosenthal, Moore), decades ago and the problems simply remain. It is not an issue of awareness at this point, but clearly power games at play. Evidently I am the first to face it with such brutal honesty.
interesting that he mentions social engineering in the manifesto. makes me think he lured the CEO somehow and that’s why he knew exactly when the target would be there. he waited for like 5 minutes before the CEO showed up, that was unrealistically precise if all you had was public information.
Stop making assumptions. The article is clear that we have 0 evidence that this is the actual.manifesto. at this point its just fanfic
it was released by a somewhat credible source and most aligned with the bits and pieces already released by the media. of course it could still be fabrication, but i’d say it’s relatively safe to think it’s real. hopefully i don’t make fool out of myself…
It could simply mean he checked his public social media and knew where he would go. Social “engineering” can be as simple as a web search.
well that would tell him the conference starts at 8am or something. based on that he could guesstimate maybe the CEO will arrive 1~2 hours before. but to narrow it down to 5 minutes? i think he would need something more.
That’s OSINT not SE
Its possible the author wasn’t aware of the difference. And since the author was likely LE, it makes sense
I could stalk a lot of people with 5 min accuracy, easy. Most people have schedules and routines. It’s not rocket science.
Or maybe he had more planned. He’s vague about the scope of what he did, as if the letter were there in case he got caught at any point.
It would provide an explanation for him keeping the gun.
