It was a couple years back on NPR, right after some shooting. And they took callers to gauge their opinion on gun laws. And some woman calls in and says "We really should just get rid of all the guns. There wouldn't be murder if we got rid of them." Her voice sounded completely serious. Never mind how many stabbings happen in the UK. Or that mass stabbing in Akihabara, Japan some years back. And that's just thinking about knives. Doesn't take much to make a pipe bomb. Or for some nut to go wild with his truck. If people feel alienated and hated enough to want to kill, they'll do it no matter what.
