Of course it does. I could easily kill you with my Fender Lead1, in fact I could take out a large crowd with it in a matter of seconds.
Same with a ballpoint pen. Or a garden rake. Or a wire coat hanger. Or a branch broken off a tree. Or a section of my fishing pole. Or a bicycle pump. Or a broomstick. Or a rock. Or a credit card. Or a flower vase. Or a can of gasoline. Or a bottle of bourbon. Or a tent stake or pole. Or a skate board. Or an eating utensil. I could do this forever, but you get the picture.
I could kill you with nearly anything in your current field of vision except your shadow, but you're probably afraid of that, too.
Lucky for you that most people, including myself, would only kill someone in self-defense. Murder is a rare occurrence in America, and has fallen dramatically since the assault weapons ban expired.
Mass shootings are committed by crazy people, and early recognition and treatment programs would not only eliminate mass shootings entirely, but also turn would-be murderers into happy productive Americans.
If you really cared about the victims, you'd be screaming for a tax-funded government crusade to end mental illness in America. Instead, you go after nice people who had nothing to do with it.
