That doesn't resonate with my experience. People know about the murder, but aren't sure what to do.
The murderer, who clearly had mental health issues (eg, having "you're fucked" on the dust cover of his personal AR-15, which he used to commit the act), was acquitted (in a trial of strange circumstances). It's baffling that none of his colleagues - who saw the message on his weapon - ever pulled him aside to ask if he was OK.
And anyway, what does this have to do with your point of holding up an unlikely / outlying example to demonstrate a phenomenon?
His colleagues likely didn't find the dust cover noteworthy. Within contemporary American gun culture, it would seem like a minor bit of braggadocio akin to a "Protected by Smith & Wesson" sticker or a "Warning: We Don't Dial 911" placard; tacky and unprofessional, but not something to take seriously. There's a whole little industry around AR-15 customization, offering thousands of options for engraved dust covers with all kinds of symbols and messages:
I am not remotely aware of this case. How does those words, or any words, on a gun case/cover relate to mental health issues? This isn't a manifesto; it is more like "guard dog? Beware of owner!" decal, or a Calvin pissing on a coexist sticker. Or truck nuts. These might be distasteful to some but is unrelated to mental health. I'd be more worried about my former neighbor who had an unhealthy love of maglite flashlights and owned like 50 of 'em. _That_ was strange.
The "you're fucked" was written on the inside of the ejection port dust cover so that it would become visible after the weapon was fired. The implication is that he was eager to shoot someone.
