Let me preface the following statement with a little bit of background info. If you were to ask those closest to me, they may say that I am prone to spending my time in a number of pursuits that they would deem a waste of time. I have been known to research topics, experiment in my pursuits and hobbies just for the sake of curiosity and expanding knowledge. All that being said, I feel like the 15:40 I spent watching the video you posted as wasted time (though I did like the first comment in the video, debunking much of the content in the video, posted by a 30 plus year firefighter). Watching that video and listening to the poster's reasoning was like Déjà vu, as many of the points being made were the same ones made and debunked time and again in the 9/11 Truther movement videos.
