A recent poll in the german magazine "Welt der Wunder" conducted by the well known Emnid Institute results in astonishing 89% of the german respondents not believing the official line 9/11. The magazine in 2010 already published the story of NATOs "secret nuclear war", where the consequences of the widespread use of depleted uranium ammunitions were explained.
Despite the best efforts of the US Government "investigators", the debunking fraternity and the mainstream media it appears that very few people trust the official 911 narrative.
Indeed, many people who might not fully understand the scientific evidence that proves 911 was an inside job are likely to a priori question the demeanor of US officials and the material used by debunkers (and the MSM) to "back up" the Government account.
Such a cynical attitude is not surprising considering all the barefaced lies we have witnessed in relation to the War in Iraq, political assassinations and the corrupt dealings we've seen between the US State and Wall Street. The psycho/social environment is not conducive towards people believing ANYTHING the US Government puts out as fact.
The 911 Debunkers are facing two insurmountable problems; the general population's propensity to disbelieve statements coming from the (discredited as a whole) US Government and the obvious hard science that has proven the attacks involved inside help.
You cannot fool all of the people all of the time !
