There should be no reason why anyone on the streets of America can not arm themselves. If they are violent why are they on the streets? If they are violent, might they be less violent knowing everyone else is armed?
Regardless, politicians love to talk about equality. A .44 Magnum makes us all equal on the streets.
Fortunately I live in the Free State of Arkansas and I am never unarmed. Concealed or open carry depending on the weather.
