This graph here clearly rectifies the argument that guns used in mass shootings are obtained illegally. Obviously, the majority of them are obtained legally (note the tall orange guy to the left), which leads me to this inference: people are not being checked thoroughly enough before they buy guns, because 79% (49/62) of the guns used in these mass shootings were obtained within the law.

Now, I don’t think we should ban guns. That’s not realistic–not only would it never pass, but it would not end the issue of gun violence. Banning guns will just move the guns to the black market. Look at Prohibition: did banning alcohol end drinking? No, it just led to organized crime and bootlegging. If guns are banned, people will just resort to obtaining them illicitly.
So, what we need to do is initiate a system of background checks. We need to check what a person’s done in their life-are they an ex-convict? Are they mentally ill? Are they predisposed to engage in gun violence for any other reason? We need to make sure people with these ‘qualifications’, so to speak, can’t obtain guns that they could use to kill innocent people. I mean, come on: it’s just common sense.
