I'm not sure. Less than half US households have at least a gun, considering 120 arms every 100 people, there's quite a concentration. Also, commonsense tell me that, if armed, criminal comes in already branding the gun, to react quickly people inside should always have a gun with them, even when inside home. I don't know if US people is used to, I would find it a terrible way of living, a way of fear.
