The way things went down in New Orleans during Hurricane Katrina will be the same kind of craziness if there is an Ebola epidemic. There will be looting, people shooting at others and people setting fires. What kind of response from the government is speculation. Maybe the kind of speculation I envision is exaggerated. A pandemic like what Ebola is able to bring is something way beyond the disasters we have experienced. The way Big Bertha Government is capable of making big mistakes, I have no confidence they will react to the chaos with reasonable care to Constitutional rights.
Even moreso, despite all that surveillance, people still regularly make it past their many eyes. I guess many eyes isn’t indefinitely powerful, and not immune to spamming the system, or hiding within a crowd. The Boston Marathon Bombing, for instance, happened in a supposedly heavily surveilled area, under plenty of cameras.
