Think bigger than bashing the incompetency of FEMA. There's sly purposfulness here and I believe that someone on Citizens for Legitimate Government may have stumbled on it:
"It was suggested to me by someone that it seems like the lack of assistance in New Orleans was meant to provoke people to extreme violence and chaos. It certainly looks that way to me... but what if new orleans is being used as a test case to see, in a real world setting, how easily a motivated, angry populace (and the military personnel forced to do the dirty work) could be subdued and controlled to create a working model of how to impose endless Martial Law throughout the country while keeping those who might resist under the lid... and those in the armed forces in line. It's a thought... because I find it absolutely incredible how inept the response has been... to the point of criminality on the part of the federal government." --c., CLG reader.
