Chances are, if we did get infected by a smallpox attack, we would be quarantined and kept in a sealed perimeter.
Vaccine would be in short supply... Marshall Law comes to mind.
In this war, civilians will be on the front line as well as the military... easier targets.
No Marshal Law will be needed.
However, until there is enough vaccine to go around for easy single person in the United States, I would give preference to registered Republicans.
I live in Houston... panicky people comes to mind. I am making just in case provisions all the same. I didn't worry about Y2K or any other doomsday stuff. BUT I am taking this seriously!
