I just checked in at a news site and see that in Kentucky there was a school shooting. One dead so far, seven wounded and the shooter is in custody. The school is being evacuated as I type this.
What is it that people are now thinking they can go in someplace and commit an act of violence? It used to be you could go out in the United States and not even consider someone in your own community employing deadly force en masse with random victims.
Other political and social issues pale in the light of such behavior, in my opinion.
