And what about the Oklahoma City bombing? He killed 19 kids all under the age of 6 with a bomb in a federal building that housed offices for the D.E.A., A.T.F, and Secret Service, not a gun, and yet you can still get the stuff needed to make that sort of weapon. The problem isn't guns, the problem is we live in a world that unfortunately has some people in it who are sick, twisted, and fucked up who have no regard for human life, be it children or adult, whatsoever. Even if gun regulations were tightened, you still have guns on the street being smuggled in illegally. If you take guns out of the equation, say you have someone who wants to do something like this, cause serious harm, they'll find something to use regardless of what it is.
