Back in the 70s/80s, newspapers in SF stopped publicizing suicide attempts off the bridge because they realized that the articles increased awareness and people were doing it to be recognized. National media coverage of mass shootings doesn’t help and likewise the arguing and virtue signaling that ensues.
Couple with isolation, social media and undiagnosed/untreated mental illness and it’s bad news. I tend to think that if guns went away, this tendency would manifest in other ways. So, it’s not necessarily a guns problem. It’s a schools and families problem. But the debate has been boiled down to that.
