It is reported that the HR 645 reports the below text: 

By Mark Anderson

A bill introduced on Jan. 22 of this year “to direct the Secretary of Homeland Security to establish national emergency centers on military installations,” as the text of HR 645 actually states as its central purpose, could conceivably be geared toward creating what many Americans have feared in recent years—detention centers, or concentration camps, on American soil.

These fears are more acute these days due to the imploding economy, swine flu scares and other fear factors—real, imagined or concocted—that could lead to food runs, bank runs, and other signs of civil unrest that may spark a government crackdown.

If you go to FEMA's website the below speech is presented at the reasons for these concentration camps.....

excerpt of the speech from:

Craig Fugate

Administrator
Federal Emergency Management Agency
Department of Homeland Security

 

"While FEMA is certainly prepared to provide a large number of temporary housing resources following 
a disaster, the sheer size, scope, nature and duration of the sheltering needs after a catastrophic 
event require us to look at alternatives, and will require the coordinated involvement of federal 
agencies, state, local and tribal governments, the private sector, and voluntary and faith-based 
groups.  As I noted in recent testimony before another House committee, disaster housing, particularly 
following a catastrophic event, is not a mission that FEMA can or will ever be able to effectively 
handle alone.   However, it is a mission to which FEMA is committed to providing national leadership.

The emergency management community has developed several very real, potential catastrophic scenarios, 
and the number of potential disaster survivors that may need sheltering and housing is enormous.  
For example, planning experts anticipate that following a New Madrid Seismic Zone no-notice earthquake,
 a projected 2.6 million people will require shelter.  It is also estimated that following a Category 5 
Hurricane in the most populous areas of Florida, as many as 3.6 million households will seek either 
short- or long-term shelter.  After a catastrophic hurricane affecting Honolulu and the island of Oahu,
 it is projected that 650,000 residents would be in need of shelter.

These numbers can increase significantly due to the unknowns - significant aftershocks, ensuing fires, 
safety and security concerns, additional significant weather conditions that could affect population 
movements, and temporary sheltering requirements dependent on seasonal weather conditions.  The bottom 
line is that neither the federal government nor the manufactured housing industry has the capacity to 
address all the anticipated housing needs in a timely manner in these types of situations.  
Because of this, we will need to rely on other, more innovative housing options.  
Although our first priority is always to shelter and house survivors in or near their communities, 
that will simply not be possible in a truly catastrophic event or an event involving contamination.  

While we continue to aggressively explore options to quickly provide or restore housing in affected 
areas, the capability will simply never exist to locally shelter and temporarily house half a million 
or more survivors.  Instead, we all need to recognize the need for a timely, organized, and 
disciplined relocation of survivors to venues where such shelter and follow-on temporary housing 
exists.  The reality is that, if a region is sufficiently devastated by a catastrophic disaster, 
it may be many months or years before recovery has progressed to the point many disaster survivors 
will be able to return to their homes and communities.  

Accordingly, we must temporarily place survivors in environments conducive to personal stabilization 
and recovery where they are, as their communities are rebuilt. Other options that must be considered 
include rehabilitating rental units that can be repaired quickly, similar to the efforts undertaken by 
FEMA in Iowa and Texas under a recent pilot program authorized by the Post Katrina Emergency 
Management Reform Act’s Rental Repair Pilot Program.  This legislation also gave FEMA additional 
authorities to undertake semi-permanent and permanent construction work to make repairs.

We must also look at ways to speed up the infusion of eligible public assistance funding to 
communities, which can be financially devastated and thus unable to commence critical infrastructure 
repair projects without up-front funding.  Spurring timely recovery at the community level will 
send a powerful message of hope to community disaster survivors, as well as create jobs that may 
prove crucial in keeping many residents in those communities.  I firmly believe that we can make
 our public assistance program less process-oriented and more outcome-driven, and we are working
 toward exactly that.  We are also working with our federal partners to improve the delivery of 
additional federal long-term recovery assistance."

In other words the reason they have these camps is in order to house a large number of people after a 
horrific event......

Believe or not to believe.  Not sure.
