One of the other contingencies they are planning for is the (possible but unlikely) collapse of the Mexican government, civil war among the narcos and mass illegal immigration of refugees across the southern border. Ditto, a change in Cuba that would open the floodgates to refugees from Castrolandia. What does your FEMA subcontractor say this project is for, since he or she seems to have the inside skinny on this?
Civil unrest and disobedience towards government deemed as a threat.
