The Best Argument I've Heard So Far
I found this video last night and highly recommend you give it 7 minutes of your life. What we have to realise is that evil people will commit evil deeds, removing the means for people to protect themselves in the hope it will stop criminals is asinine. Passing laws will only effect law abiding people, and that is the problem with criminals, they tend to not obey the laws. Again look at my country South Africa where it is virtually impossible to buy a gun, we are the second worst gun violence country in the world.
"The laws that forbid the carrying of arms are laws of such a nature. They disarm only those who are neither inclined nor determined to commit crimes.... Such laws make things worse for the assaulted and better for the assailants; they serve rather to encourage than to prevent homicides, for an unarmed man may be attacked with greater confidence than an armed man." -
