This story first popped up a few days ago; at the time I dismissed it as “just recruiting guards for Guantanamo or Leavenworth”.
Then I got to thinking about it some more, looked around a bit, and saw that guards at Gitmo and Abu Ghraib are either Regular Army or Army Reserve (in the case of Gitmo, that includes their Navy counterparts), not National Guard. I would imagine Leavenworth is Regular Army MPs, also.
Another possibility could be that the NG just realized all their existing folks in that MOS have gotten out to go to work for civilian prisons, but, using California as an example, I don’t think they’re hiring a whole lot these days.
I’m not having a whole lot of luck coming up with a “harmless” explanation.
That would suggest there’s not one.
The question, then, remains.
My view was that the National Guard, while unusually called up to Iraq, is a national defense force and we have no natural enemies that intend to invade us anytime soon. So, this is a force to be used against Americans.
Katrina did not use nor need internment or resettlement, not by a militarized force anyway.
