Bro, as I've said before. Guns aren't the root. The sick minded individual is. That kid could have easily googled how to make a damn bomb, go into the janitors closet and find exactly what he needed to possible kill even more people. The problem with the gun control debate is that people blame guns. The way its seen is thats the problem. Taking them away would awaken a whole other method of murder. Until we live in a perfect society, the ability to protect ourselves is needed. Typically, the anti gun lobbyist are the first to change their mind when something happens to them.
That's an understandable point of view, but the ease of acquiring an assault rifle isn't going to deter someone, compared to someone making an IED. Mental cases will always exist. But what it has done, is brought bigger issues to light. Depends if you still believe this is just about one mental kid and a school, or if it's about the ease of which a massacre could occur.
