You and you alone are the ultimate guarantee of your own safety and that of your family. No one else may be willing or able to protect you. No one else is guaranteed to be there. Take a moment to reflect.
Remember the LA riots? Remember the sack of Rome? Remember the legend of Troy? Remember Hurricane Andrew? Remember the great San Francisco earthquake? Remember Beruit? Remember the great Chicago fire? Remember Nanking? Remember Pompeii? Remember Sarajevo? Remember Rwanda? The total breakdown of law and order happens several times each DECADE. It can and has happened here. Don't bury your head in the sand.
If you can afford to provide those things for yourself, why would you neglect to do so and further deplete the disaster supplies available to those who cannot afford to? Take responsibility for your own welfare, no one may be able or available to help you.
