If guns were illegal, people will still kill using other methods such as knives, swords, bombs and many many other ways. Use COMMON SENSE that it's not gun's fault, it is people's stupid brains fault.

By the way, I don't believe in god because I have been dead for an hour and life is just a joke. You are alive to experience everything and when you die, you use all of your knowledges,experiences and visuals to make your "imaginary world" so awesome. When you die, DPT from your brain kicks in. If you don't know anything or have experienced DPT trip then start reading so you have nothing to be afraid of about death.
