While I do think that there needs to be some massive reform in regards to gun laws in the states, a few posters made the point that illegally purchased firearms are a massive issue. While others shot that idea down (poor metaphor I know). Having lived in close proximity to cities where there was major gun violence, the highest in America per capita, I would agree that illegally purchased guns are indeed a huge problem in Americas cities, where most of the gun violence occurs.

Last year alone Chicago ended 2016 with 762 homicides, many of which were gang related...

Something that I do not forget having lost friends in Afghanistan and having friends both living in Chicago and working as policemen in Chicago.
