Baton Rouge would have been perfect as the refuge. Right next to the capitol, along with Alexandria, both of which were anticipated to be just outside the bubble, as of Sat Am. When a place is headed for destruction, one doesn't place folks in the bowl of the destruction. One gets them out, and does it with public assets, trains, planes, boats and buses, all of which were inoperative as of Sat AM. Then after the bullet was dodged, the deer in the headlights continued, from top to bottom. There was a lack of intensity. It was too slow. It is still too slow. The whole thing is criminal. Heads should roll.
Here is my short answer, as posted to Howlin':
As for assisted or "enforced" evacuations, I already posted about this, you cannot force people to leave who don't want to leave. They will hide, they will waste your time by arguing or resisting, and you need all your emergency staff and equipment at the crisis point, not somewhere between New orleans and Baton Rouge.
