I remember during Katrina many people had improvised crudely mades signs stating that looters would be shot. Many stood guard outside their homes, and in some neighborhoods neighbors had formed an armed possey. I'm wondering what happened after order was restored or even during the SHTF situation. Did LE conduct in depth investigations into shootings during SHTF? What about after? I wonder how many people killed looters and no one knew about it... Or were they all investigated?
