I think one of the reasons we've seen seemingly growing numbers of mass shootings in the U.S. is because such acts are far more prevalent in the public consciousness. At this school where the shooting took place today, the staff had actually done a safety drill involving shooting a gun with blanks. Thirty years ago, it probably would not occur to a troubled teenager to go into his school and shoot indiscriminately at his classmates and teachers because it simply wouldn't have occurred to him to do so. The mental model for doing so wasn't so ubiquitous.
Since Columbine, the way the media has fixated on and sensationalized these shootings has created a sort of "meme" out of the act. Similar to "suicide contagion" or copycat terrorist acts, I think there has emerged a "mass shooting contagion" where a seed has now been planted in vulnerable people's minds that wasn't there before. Now we have schools doing "mass shooting drills" and it's even devolved into a throwaway joke on TV, movies, and on stage (in Dear Evan Hansen, Jared accuses Connor of looking like a school shooter).
Then we have the fact that Reagan shut down the mental institutions (which were often terrible and deserved to be shut down), but replaced them with... nothing. I was in school not all that long ago. The way many schools are run these days is akin to a prison. Kids are anonymous numbers, and the way we write off "delinquent" students and their victims (both often suffering from trauma at home, poverty, abuse, criminalization, stigmatization, etc.) only exacerbates things.
