Via Friends of Liberty:
There over 800 prison camps in the United States, all fully operational and ready to receive prisoners. They are all staffed and even surrounded by full-time guards, but they are all empty. These camps are to be operated by FEMA…
The camps all have railroad facilities as well as roads leading to and from the detention facilities. Many also have an airport nearby. The majority of the camps can house a population of 20,000 prisoners. Currently, the largest of these facilities is just outside of Fairbanks, Alaska. The Alaskan facility is a massive mental health facility and can hold approximately 2 million people.
