Yep. The best thing to do is to have enough supplies to stay self-sufficient.
Even a couple of weeks worth of groceries will put you ahead of 99% of the sheeple.
Another big lesson here is that the police aren't going to protect anyone except themselves when the SHTF. Many of us in the RKBA community have been saying this for years, but after NOLA, perhaps more people will realize it.
Only a few percent of the sheeple will use the NOLA lessons as a wake up call. Most sheep just want a shepherd to lead them.
