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.
