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

>>The footage broadcast by CNN was approved by the parents of the victims, as they hoped that showing the footage would spur action to prevent future shootings………

It will do nothing. I'm convinced they could show videos of the actual shootings happening with the blood and the cries and screams of terror, and it will not move some in state leadership to do anything meaningful. They're cowards.
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.
