When rioting happens that threatens people and property or looting following natural disasters, people pull together to protect their neighborhoods and property with firearms. Whether is is people outside New Orleans sitting in folding chairs with shotguns and signs saying looters will be shot or Korean businessmen during the Watts riots standing guard on the rooftops of their stores, people will step up.
If Democrats continue to reduce police budgets, soon we will see neighborhood vigilance committees being formed. It is just a proud tradition in the Western US going back a long time.
Geez, I might have to get me one. :-}
