If a crazy person drove a car into a playground and killed a bunch of kids would it be wise to make laws to have background checks to buy cars? If a dog got into a school and killed some kids would we make it harder to own dogs?

Even if we were to magically make guns disappear around the world, people would still kill other people, they would merely use other tools to do it. What are you going to do when suicide bombers come to this country? I have no doubt sooner or later it will happen here and we are not prepared for it.
