This is 'good news' in the sense that it brings this subject back into the collective, media driven consciousness of our otherwise brain dead society. However, I'll point out up front that I don't get too excited about these 'revelations' because they are based on-- and further perpetrate--the conspiracy theory advocated by our government: that the events of 9/11 were caused by Muslim terrorists.
I want to make it quite clear that I DO NOT BELIEVE, given the evidence, the "Muslim terrorist" theory is credible. I do not believe that a Boing 757 hit the Pentagon on 9/11 (See:
http://physics911.org/net/modules/news/print.php?storyid=3 AND
http://911research.wtc7.net/talks/pentagon/index.html ). Moreover, I do not believe that "fire from jet fuel" (essentially kerosine) was responsible for the collapses of buildings 1 and 2 of the World Trade Center. Nor do I believe that building 7 collapsed at 3:30 in the afternoon as the result of damage by "fire." Steel, concrete and glass structures do not "collapse" as a result of fire, PERIOD. The only thing that can cause buildings to implode and collapse straight downward is explosives--and accurately placed and timed explosives at that (See:
http://911research.wtc7.net/talks/towers/index.html AND
http://911research.wtc7.net/talks/b7/index.html ).
I do not claim to know what happened on 9/11 but I am certain that what the government has been telling us did NOT happen. For the events of 9/11 to have been caused by "Muslim terrorists" they would not only have had to have had access to high levels of our military command structure in NORAD, they would have had to have planted demolition devices in buildings 1, 2 and 7 of the WTC AND been able to crash either an F-16 or a winged (drone) missile into the Pentagon. I do not believe "Muslim terrorists" have any such capacity.
THEREFORE, hearing that the "attacks" were "preventable" is what those of us who study such things call a "limited hang out." That is, it is a "revelation" which, rather than actually revealing the truth of a matter, reveals some part of it while simultaneously deflecting attention away from the most serious, and usually damning, questions and issues.
