Yeah, so far this basically sounds to me like if the guy from Falling Down walked into the building Patrick Bateman works at.
At worst, from a tactical effectiveness standpoint.
If it actually was a more or less specifically targeted attack, it would absolutely make sense that this would be massively underplayed and misconstrued by the broad media...
Because the last thing the broad media wants, is a lot of pissed off, suicidal, heavily armed Americans realizing that this can actually be a shockingly effective tactic, for those with nothing left to lose, ready to meet God or w/e.
The broader media being basically a totally corporate owned affair, that really, really would prefer it not become normalized that ... (semi?) random corpos just start getting gun downed in roughly the American version of insurgent suicide tactics, who are to a great extent capable of acting totally solo and are thus impossible to completely prevent at scale.
Call it the 'final form' of 'I'd like to speak with your manager'.
