Tumeric has kindly commented (blowing sky high our mutual and illicit transatlantic chocaholic attractions - in which Trader Joe's has a rather important role) and she has posted on the topic of NPSD 51 - she points us all to a discussion on Kos that started simultaneously with the Lord Patel's original post about NPSD -51 here
Most interesting comment (of 526 and counting) is this ..
The Miami Herald's Alfonso Chardy wrote a story on July 5, 1987 that linked Oliver North to FEMA planning from 1982-1984 to suspend the Constitution in the event of a national crisis. Jack Brooks (D-TX) tried to ask North about this in front of the cameras, but Chairman Daniel Inouye (D-HI) cut him off by saying that the question dealt with classified matters. Which you can now watch - the interesting bit starts at about 1 minute.
... it does all make you wonder about those camps that Halliburton was building.
