What you said in regards to poverty, institutions, education etc i agree with 100%. It's more of an overall culture and failing in so many areas, IMO.
Honestly the more i read about it i don't think gun law has much to do with high murder rates, or very little. Suicides, domestic's etc , ok maybe a stricter law would help some, but mass shooting and other violence? I don't know.
Most of the gun violence (not sure of actual stats but i think it's a good assumption) in cities like DC, Baltimore, Oakland, Los Angeles, Chicago etc i think are overwhelmingly gang on gang or drug related and take place in specific neighborhoods. I would bet that a lot of those people all carry guns. I don't think a huge portion of the violence is criminals picking on regular civilians because they think they aren't armed.
@ Blu, when i talked about lax gun law, i should have been more specific. It was permissive gun law which i think is open carry without a license. I don't know a lot about it. It was also OVERALL gun deaths, not just violence related. I might have misunderstood things because I'm surely no expert. If I'm wrong, feel free to correct me as i sometimes jump to conclusions.

Also, check my link on page two. That article really opened my eyes on some things or at least made me think about it in different way.
