There is one small step that could be taken without legislation that can’t hurt, and may even be a small deterrent to would-be mass killers.
I happened to see part of a TV talk show where the question being asked was, “Why do people commit mass shootings?” One of the commentators said that a contributing factor is that the killers like the notoriety associated with their act.
The media always call people like Paddock, Dylann Roof and Cruz the “shooter” or the “gunman.” Wyatt Earp could have been considered a “shooter” or a “gunman” (the term a would-be mass killer may consider a badge of honor), and Wyatt Earp had his own TV show. We should be referring to the Cruzes of the world as “loser,” “scum,” “failure,” etc. Even Roof might not be so impressed with the headline, “Another chicken**** loser fires up a church.”
Maybe a change in terminology wouldn’t help at all, but it couldn’t hurt, and the media wouldn’t have to battle the National Rifle Association to implement it.
