Mass killers have a desire for infamy and attention. We call it narcissism. We can’t know whether withholding names and photographs of mass killers from coverage of their crimes would play a factor in the future decisions of others evil enough and/or mentally ill enough to contemplate mass murder. But, even if it plays a small role in preventing some from playing out their anger and frustruation, it wll at least not give them the attention they crave.
Media currently withholds names of confidential sources upon who the credibility of their stories rests. Media also withholds names of survivors of sexual assaults from stories about the crimes against them. Let's ask them to withhold names of mass killers.
Let's stop giving people permission to broadcast their anger or frustration by killing a lot of people. Let's stop rewarding killers who want attention.
