It's not, though. Something has changed. My father literally used to bring his rifle to school for the target shooting club (not sure the exact name). If you can blame guns, then you can also blame the internet because that's where a lot of these young men spend their time in insolation, amplifying their violent fantasies. You saw that with the Sandy Hook shooter. He put garbage bags over his windows and didn't come out of his room for weeks at a time.
