Shooter incident at elementary school in Uvalde, Texas - 19 children and 2 adults dead

I think you are wrong. When the news shows stuff like that, it does have effect. It's unavoidable unlike a broadcast sanitized to protect our delicate sensibilities.

If there was one lesson learned from Vietnam it was, don't show the images. IDK which is more disturbing, the images themselves or the reason we don't see them anymore.
I would like to be wrong. But Texas has a few mass murders recently in El Paso, Sutherland Springs, Santa Fe High School, Uvalde and Allen. Mostly what I've seen done is thoughts and prayers. We just had an election last year where the positions that could make the most change were up for election, and the same people remained in office.

I agree that some of the images should be shown with the usual caveats of "We must warn you, the following images we are about to show you are disturbing and difficult to see. You may want to look away to avoid seeing them."
