Alex Jones, the guy who runs that site, is more than a little nutty. I read alot of conspiracy theory and agree with a little bit of it, but not too much. I guess it would depend on what one considers "conspiracy theory." That said, US outsourced internment camps don't seem out of the question. Read some more on Prisonplanet and you'll see why I think the site is nuts. I was reading a site the other day saying that Alex Jones is himself an Illuminatus and I had to restrain myself from falling off the chair laughing. If you are interested in conspiracy "theories" that the Freedom of Information Act ultimately validated, look up "MKULTRA" and "Operation Northwoods." It's a shame legitimate concerns like that get overshadowed by that **** about "chemtrails" and the like.
The pen may be mightier than the sword, but why pick just one?
