911 conspiracy and Alfred Rattera

Well, seems like this guy gets everywhere, been doing my usual search on conspiracy theories and and came across this guy blogging from the UK. Claims Rattera was killed by the American Government because he knew about September 11th attacks. Specifically that the USA govt. was involved in some form. He is not the most reliable of 'characters (You will see what I mean when you read his other posts). But this theory is certainly very interesting. Further he goes on to say that maybe there was a specific campaign against him and the foundation that was set up to monitor his work. Link to his rambling post here. Does add something significant to the argument though.
