The people that want to ban guns, or put harsh gun control restrictions in effect, are basically simplifying a very complex issue. It's actually the same line of thinking that gets us a big wall on the border to deal with illegal immigration. These solutions ignore the cultural and economic realities of the United States.
It would be nice if we could really get serious research done on both these issues without constant political bickering and see actual targeted reform put into effect. But I suppose would also be unrealistic.
