Here's the most comprehensive report I've seen yet to justify 9/11 as an inside job, and thankfully ties in the criminality of former CIA Director G. H. W. Bush as both Vice President (to clueless Reagan) and President.
"[N]ot only were the buildings targets, but ... specific offices within each building were the designated targets. ... [T]he attacks of September 11th were intended to cover-up the clearing of $240 billion dollars in securities covertly created in September 1991 to fund a covert economic war against the Soviet Union, during which 'unknown' western investors bought up much of the Soviet industry, with a focus on oil and gas. The attacks of September 11th also served to derail multiple Federal investigations away from crimes associated with the 1991 covert operation.

"The U.S. Subprime and global financial crises of 2008 was the direct result of a covert monetary policy implemented by the U.S. financial institutional caretakers of the World War II Black Eagle Gold Fund."

The above provides motive for the insiders. Below is proof of insider involvement as documented by the NIST Final Report on WTC-7. NIST writes with emphasis added:
"In stage 2, the North face descended at gravitational acceleration as the buckled columns provided negligible support to the upper portion of the North face. The free fall drop continued for approximately 8 stories or 32.0 meters (105 feet), the distance traveled between times t = 1.75 and t= 4.0 seconds."
Gravitational acceleration means freefall; the entirety of stage 2's potential energy was converted into kinetic energy (accelerating downward motion); and no energy was available to destroy columns, floors, or building content. (Even if we accept the theory of how heavily damaged WTC-7 was without exploring how it got so damaged and when) how could 8 stories of columns (whether or not weakened), floors, and material suddenly transition into negligible support?
The ramifications of freefall in any stage of collapse in any of the WTC buildings is additional energy sources (like explosives) has to be planted and therefore the circle of 9/11 conspirators was much larger and included insiders.

"Perhaps the greatest fantasy of the present moment is that there is a choice here. We can look forward or backward, turn the page on history or not. Don't believe it. History matters.

"Truth, through her eternal laws, unveils error. Truth causes sin to betray itself... Even the disposition to excuse guilt or to conceal it is punished. The avoidance of justice and the denial of truth tend to perpetuate sin, invoke crime, jeopardize self-control, and mock divine mercy."
