will have guns.

Look at a list of US cities and their laws regarding guns. You have D.C. our capital that until recently even cops could not keep guns in their homes and it was one of the most dangerous cities in the world. Ditto NY City Baltimore, Chicago etc. Look at cities that allow gun ownership like Houston and Dallas while by no means are you safe walking through downtown in the hood at midnight flashing a wad of cash but the fact that you may have a gun is a deterent.
