Please, don't panic....yet. But do have a sensible, workable plan.
If it is possible, place some of your assets into physical silver and gold.
Make sure every time you go to a "big box" store, that you buy extra durable goods. Have critical medications you and your family - and your pets - may need stockpiled.
Have communications devices which are not dependent on cell-phones. A couple of good two-way radios can be a good investment.
Think about how you will defend your home, if need be. Police are only good for cleaning up a mess after a crime; not preventing it.
If you need to meet in an emergency, make sure the family knows how to get back together, and how to get the heck out of Dodge, if you need to.
