Concerning 9/11 and the Commission Report, should we question authority?

It seems the 9-11 Commission left out a lot of details, like tracing the funding for such an attack, what happened to building 7. The whole report was approved by the Bush administration. Do you accept authority as truth or are you willing to search for truth as the authority? We need an independant investigation. There are too many coincidences and unanswered questions.
