I noticed when people said “Oh no, not another school shooting! Poor kids, they must have been scared! They really must do something about gun control over there; they have more school shootings in a year than other countries have in half a century”. I noticed little or no speculation about the gunman, either way.
Trump Derangement Syndrome:
You realize that Republicans make up about half of the population, right? If gun attacks are just the way things are; “nothing we can do about them”, about half of the gun-killers would be Republicans. Finding ONE non-Republican shooter, after a long list of Republican shooters is not a sensation. That they are so few is a sensation.
Huntsmen and gun-enthusiasts can probably be found in both “camps”, but the ones hoarding semi-automatics seems to be prone to vote red. (I find it funny that Red used to be the color of Communism, but now it’s the color of right-wing politics in the US.)
I read that when you use an AR-15 at close-range on a person with no body-armor, it’s like as if a hand-grenade has gone off. It’s built to pierce metal helmets 500 feet away.
