Thou shalt not know thy neighbor in a city. Neighbors are supposed to be strangers. They might be devil worshippers or even worse, Republicans. Everyone in a city is out to kill you. Whether you are out walking your dog, jogging through the park, or standing in line at the liquor store, someone within a few feet of you is carrying a gun and might kill you.
Guns are evil.
All those strangers around you are carrying guns. You don't have one because you are afraid to use a gun. But those other scum are carrying heat. Therefore all guns in a city must be banned, especially the ones owned by those strangers. Rifles are ok, because they are owned by strangers who live in the country far away from you.
