On page one of the document, it says - "DESTRUCTION NOTICE: Destroy by any method that will prevent disclosure of contents or reconstruction of the document."
The document is dated February 2010.
According to the documents shown in the video, the indication that the internment camps are meant for Americans is the instruction that a social security number be placed on the paperwork for "prisoners."
Then on page 56 of the document:
3-56.The PSYOP team also supports the military police custodial mission in the I/R facility. The team—
• Develops PSYOP products that are designed to pacify and acclimate detainees or DCs to accept U.S. I/R facility authority and regulations.
• Gains the cooperation of detainees or DCs to reduce the number of guards needed.
• Identifies malcontents, trained agitators, and political leaders within the facility who may try to organize resistance or create disturbances.
• Develops and executes indoctrination programs to reduce or remove antagonistic attitudes.
• Identifies political activists.
Watch the chilling video below, then go read through the document.
[Update] From the preface:
This manual continues the evolution of the I/R function to support the changing nature of OEs. In light of persistent armed conflict and social turmoil throughout the world, the effects on populations remain a compelling issue. The world population will increase from 6 billion to 9 billion in the next two decades, with 95 percent of the growth occurring in the developing world. By 2030, 60 percent of the world’s population will live in urban areas. Coexisting demographically and ethnically, diverse societies will aggressively compete for limited resources.
Typically, overpopulated third world societies suffer from a lack of legitimate and effective enforcement mechanisms, which is generally accepted as one of the cornerstones of a stable society. Stability within a population may eliminate the need for direct military intervention. The goal of military police conducting detainee operations is to provide stability within the population, its institutions, and its infrastructure. In this rapidly changing and dynamic strategic environment, U.S. forces will compete with local populations for the same space, routes, and resources. The modular force’s ability to positively influence and shape the opinions, attitudes, and behaviors of select populations is critical to tactical, operational, and strategic success
