Global Research has a long article, talking about something known as "Continuity of Government," where, in states of emergency, a shadow government has the authority to run things. In such a situation, journalist Christopher Ketcham reported:
"There exists a database of Americans, who, often for the slightest and most trivial reason, are considered unfriendly, and who, in a time of panic, might be incarcerated. The database can identify and locate perceived ‘enemies of the state’ almost instantaneously.” He and other sources tell Radar that the database is sometimes referred to by the code name Main Core. One knowledgeable source claims that 8 million Americans are now listed in Main Core as potentially suspect. In the event of a national emergency, these people could be subject to everything from heightened surveillance and tracking to direct questioning and possibly even detention.”
So spying on us helps them to know who is an "unfriendly." I'm going to go out on a limb here and guess that I'm on their list. I can't see them packing all 8 million of us in Guantanamo. I wonder if we get to pick the detention center we prefer.
