We gave everyone in America that power when we decided that basically anyone can buy an assault rifle. I don’t pretend to understand the motivations of these shooters, but ultimately it has to be at least a little bit about power, right? They’ve been convinced that having power is how you measure your worth, and they are sad or angry or, as is so often the case, both, and they see that there’s one way they can definitely change the world. They’ve seen a dozen other guys do the same thing, so why not them?
