It seems to me, that as long as we continue to manufacture firearms and other weapons, people will continue to use them for their intended purpose; killing people.
If so I cannot see any justifiable reason for this practice to continue. What person is proud to produce a tool for killing. There can be no defence of gun violence against the guilty because the innocent are victims as well. A hunting rifle is one thing but handguns and assault rifles are expressly for killing people.
Let's stop making guns. We can do it.
How, in good conscience, can we not?
