If gun were restricted on the whole US, the guns would not be so easily available. The problem is, many do not want to restrict gun in any fashion. Therefore gun bought in a state can legally or illegally very easily go from one place to the next.
This is a much different proposal when gun are restricted country wise. Sure people can illegally get guns, but the probability is much lower, and more importantly, they don't expect other to have gun and are less likely to use them against random people.
We had a gang criminality where I live just like you had. But you know why it rarely do the news around where I used to live (well except when they started to burn all those car around Paris) ? Because when they fight and go to the hospital it is because of using knives, or bludgeon. That need far more guts and go body to body with the intended victims, than pressing a trigger. That still happened because there are such people everywhere. And guns, the very rare which was for sale, were a very very rare occurrence.
The point is NOT to make guns impossible to get, the points is to make them unavailable not readily available, a costly rare occurence.
if you have widespread gun sale to everybody, then those will *always* be widespread among the thugs.
Accept the dead and accept the gun non-control. Or refuse both. You can't chose and pick.
