Quit making sense by isolating variable.This stuff didn't happen nearly as much before the late 90s. It's cultural rot, probably prescription drugs, and broken homes more than guns. Guns have always been around this country.There simply are no countries where firearms are not a leading cause of death for children. Nothing can be learned. Nothing can be done.Living as a human on Earth is inherently dangerous. Unlike most libs, I prefer to accept that risk at the benefit of preserving my personal freedom, including having the ability to defend myself and my family. Utopia is impossible.
