Before conspiracy theory culture went mainstream via the last presidential administration, there were the 9/11 truthers, led by orgs like AE911Truth. These orgs do real damage to peoples' lives, such as convincing surviving family of 9/11 victims that the US govt planned the attacks and covered up a conspiracy to bring down WTC7.

It takes slightly more than a casual interest to draw the correct conclusion that WTC7 fell from uncontrolled office fires. In this case, reputable scientists and engineers at NIST did the analysis work for us.

One wouldn't be faulted for casually examining a collapse video of WTC7 and preliminarily concluding that the tower fell from some type of controlled demolition. Of course, further examination of the video negates this conclusion.

WTC7's collapse could be a project for a critical thinking skills class for high school students.
