Preserve the crime scene. Follow the money trail. Establish the motive. Look for those with the means to pull off the crime.

No attempt to preserve the evidence or establish the means, motive or opportunity. No inclination to follow the money. The 9/11 commission itself concluded that the funding of the attacks were of “little practical significance.” From the very first moments after the attack, the fix was in.
