Some good points.  But you can point out crime with guns in any big city and the response by those who want stricter gun laws will be the same.  They will divert the discussion any way they can because "guns are the problem."  Chicago is the point of discussion because it has so much black on black crime that liberals don't want to talk about.  And so much murder almost daily.  BTW, if you want to offer a web site other than wiki, I will be glad to take a look.
