Plenty of urban areas in concealed carry states (a large majority of the 50 states) and well over a decade of experience. Firefights simply don't break out. But of course there are many restrictions. Same with firearms in the home, people just aren't shooting the pizza delivery boy. NY, DC, Chicago, wouldn't be any different. Ironically, those cities are overrun with firearms, many illegal, as it is.
I read the NY papers online and it seems like not a week goes by where some innocent isn't killed in a cross fire. And that is when guns are harder to get. Don't forget that, as you say, EVERYWHERE, there are some restrictions. The absolutest want none and I wouldn't want to be part of that experiment.
Last week I found myself defending Gays and now I find myself defending gun laws. I want to do neither.
It's just that the extremists against Giuliani use what was a common sense policy for a Mayor of a huge diverse city to extrapolate that he would have abhorrent policies nationwide as President- policies that I believe actually would never even cross his mind were he President.
