Catastrophe do you want to be armed or would you hunker down?

If a catastrophe like Katrina or Haiti but 5 times worse happened and the government was basically out of commission, and seem like it would for days maybe more than a week would you want to be armed? What if you were prepared, you have supplies to last a couple of weeks until order and services was restored but many around you didn’t. If they should learn you have food and water etc when they are running out or have run out, would you want to be able to repel them if they came after the supplies that might ensure you and yours survive? And what if you were not as well prepared and what little you had you really needed to keep, would you want to know you can protect it incase there was no functioning government to do it or they were too far away and could not get to your area? Or would you rather try to barricade yourself in and hunker down hoping that you can make your home a fortress and just wait it out while keeping anyone else out?
