This is the classic, brilliant riff on 9/11, posted on September 11, 2011 to YouTube by the wonderful James Corbett, which has received millions of views and tens of thousands of votes of admiration.
The comment of one viewer sums it up perfectly:
“I just watched this again for the ~15th time since 2011. Corbett really should receive some type of global recognition for this masterpiece. In less than 5 minutes, he brings up virtually every major anomaly with respect to 9/11, while simultaneously provoking those who cling to the official narrative.”
