One of the big problems police face both before and after every disaster is getting people to leave their homes and go to the refuge areas.
People are so afraid of looters grabbing their stuff that they are willing to put their lives in jeopardy.

Would I camp on my own property?
I might, if it was safe.
If it was just to guard salvage likely not.
Most salvage operations can be completed in a day or two.
If you have any really high value items you will have a good idea of where they should be in the rubble, but life comes before stuff.
